Mechanical and nanotribological properties of Ti/MoS2 coating were obtained by carrying out nanoindentation, nanoscratch and nanowear tests at low loads. It was observed that Young's modulus and nanohardness of Ti/MoS2 coating decrease with increasing load. The coefficient of friction also decreases with the increase in sliding distance, which proves that Ti/MoS2 coating have self-lubricating property. The wear rate of Ti/MoS2 coating increases from 5.7 × 10−10 mm3/Nm to 2.1 × 10−9 mm3/Nm with the increase in load. Scanning probe microscope images of Ti/MoS2 coating shows the plastic flow of coating with no debris and cracks on the surface.

A parametric study is conducted on different group factors such as the abrasive action of the medium, engine design parameters, and engine physio-mechanical properties of the materials. The model reveals that it accurately predicts the effect of numerous factors on the wear process for the piston ring and cylinder sleeve. The model capabilities are demonstrated by the impact of air filtration efficiency on the engine component wear rate. It is found that dust particle size and concentration have significant effects on piston ring and cylinder sleeve wear rates. The numerical results show that the wear rate of both the piston ring and cylinder sleeve can be reduced by 80% when the air filter efficiency is increased from 97.8% to 99.4%.","PeriodicalId":14460,"journal":{"name":"International Journal of Surface Science and Engineering","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2020-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44353223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Injection water jet peening is a new way of inducing compressive residual stress in the surface layer. A carburised 18CrNiMo7-6 gear steel was tested using injection peening under different conditions. The main variables included pressure, nozzle velocity and stand-off distance. The surface hardness was improved up to 63.4 HRC from its original hardness of 56.3 HRC. The maximum residual stress reached −1,240 MPa at a depth of 150 μm. The results also showed that pressure has the most dominant effect on the CRSF. Metallographic photos showed that the grain size was refined in the subsurface layer, a phase change having occurred because of the peening. It was also found that the average surface roughness was inversely influenced by peening, suggesting a new role for water jets in the finishing process.","PeriodicalId":14460,"journal":{"name":"International Journal of Surface Science and Engineering","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2020-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46681418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study focuses on the tribological performance of three different lubricants, pure neem oil, neem oil with 0.5 wt.% of ionic liquid tetrabutylammonium bromide (C16H36BrN) and neem oil with 0.5 wt.% of ionic liquid tetrabutylphosphonium bromide (C16H36BrP) in steel to steel interface. Considerable friction reduction and anti-wear capabilities have been confirmed when neem oil is added with 0.5 wt.% tetrabutylphosphonium bromide. The use of this fluid has reduced the frictional force at a uniform rate, and deep, broad wear scars or blisters or eruptions on the sides of the wear scars are not seen. The viscosity, density and wear resistance values also support this conclusion. The outcome of the research shows that neem oil along with tetrabutylphosphonium bromide can replace the existing conventional, unsustainable hydrocarbon and synthetic-based lubricants.","PeriodicalId":14460,"journal":{"name":"International Journal of Surface Science and Engineering","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2020-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47645476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In ultra-high speed grinding this issue is particularly complex because the thick air barrier rotating with the grinding wheel prevents the fluid from reaching the grinding zone. In this paper, results of experiments conducted to characterise the application of the wrap around nozzle (WRN) to the ultra high speed plunge surface grinding are presented. Experiments were conducted in a peripheral wheel speed ranging from 50 to 380 m/s and the effects of the nozzle position. This efficiency was compared to a cooling system composed of double air scrapper and a conventional jet type system. Experiments showed that the WRN has higher and much stable cooling efficiency in the ultra-high-speed range of the grinding wheel.","PeriodicalId":14460,"journal":{"name":"International Journal of Surface Science and Engineering","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2020-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44669507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two main friction lining specimens in the shape of brake-pads containing treated wollastonite (Wt) and untreated wollastonite (Wu) were produced to carry on the experiments. All produced samples were characterised and examined for their mechanical, chemical and tribological properties. The experimental results show that all parameters of tribological performance are within the acceptable standard range and that the tribological performance for all samples is almost the same in terms of friction coefficient and fade performance. Regarding wear, recovery performance and disc temperature rise (DTR), Wt samples offer better performance than Wu samples which was attributed to the good adhesion between wollastonite and the polymeric matrix after treatment. Moreover, scanning electron microscopy analysis is done on the tested samples and show overall improved surface of Wt than Wu. Finally, for full use of wollastonite silane-treatment advantages, it is recommended to be used in vehicles with less severe operating conditions such as motorbike and alike.","PeriodicalId":14460,"journal":{"name":"International Journal of Surface Science and Engineering","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2019-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46194102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, density and elasticity of PEEK is closer to bones compared to metals. Nevertheless, the hydrophobicity of the PEEK surface causes a soft tissue formation at the bone/implant interface that prevents direct bone apposition. Although numerous methods have been developed for improving PEEK's bioactivity, the most widely used and accepted method have been coating the surface with a thin layer of osseointegrative material by thermal spraying. Most widely used coating materials in the manufacture of orthopaedic implants have been hydroxyapatite (HAp) and titanium.

With the increase of normal loads from 50 N to 80 N the wear rate of coated sample increases from 4.59 × 10−5 mm3/Nm to 6.86 × 10−5 mm3/Nm, while the sliding speed remains constant.
