Injection moulding is a very attractive option, however, wear and surface damage can be detrimental to the lifespan of replication masters. In this research, austenitic stainless steel inserts were hardened by low temperature plasma carburising and then different micro and nano scale surface textures, inspired by Lotus leaves and Springtail skins, were laser fabricated. A commonly available talc-loaded polypropylene was used to produce 5000 replicas and thus to investigate the evolution of surface textures both on inserts and replicas together with their functional response. The progressive wear or surface damage on the inserts during the injection moulding process had a clear impact on surface roughness and peak-to-peak topographies of the replicas. In general, polymer replicas produced with the carburised inserts retained wetting properties for longer periods compared with those produced with the untreated replication masters.","PeriodicalId":23331,"journal":{"name":"Tribology - Materials, Surfaces & Interfaces","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2020-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/17515831.2020.1785234","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43386703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It involves dispersion of various types of nanoparticles in different concentrations in the conventional lubricant and studies the tribological properties of these lubricants on a particular tribopair under different operating parameters. Nanoparticles can be considered as potential lubricant additives. They present several major advantages compared to organic molecules currently used as lubricant additives, which include their nanometre size allowing them to enter the contact area easily. The real contact area is decreased when nanoparticles are entrapped between the mating surfaces. They are often efficient at ambient temperature. Thus, no induction period is necessary to obtain interesting tribological properties. Further, nanoadditives also improve the thermo-physical properties of the lubricant. A comprehensive review is provided with the aim to analyse and explore tribological and thermo-physical properties of nanolubricants on various tribopairs used for engineering applications. Recent advancements like hybrid nanofluids and biolubrication are also discussed that further provides the solutions for sustainable lubrication.","PeriodicalId":23331,"journal":{"name":"Tribology - Materials, Surfaces & Interfaces","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2020-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/17515831.2020.1785233","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41275369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The samples were sintered at 1200°C in flowing argon atmosphere for 1 h. The physical properties such as sintered density, relative density and porosity were studied. The microstructures and phase studies of the Ni-Cr based composites were conducted using SEM analysis while the hardness of the composites were measured by Vickers Micro Hardness Tester. The friction tests were conducted with ball on disc configuration following ASTM G-99-95a standard. The MoS2 solid lubricant provides best lubrication at room temperature which is demonstrated by a low friction coefficient compared to pure Ni-Cr composites (0.176 compared to 0.394). The SEM pictures of worn out showed into evidence plastic deformation, solid debris distribution, and filling of pores with solid lubricant phases. The time taken for stabilization of friction coefficient also varies with the type of solid lubricant. Dual and multiple addition of solid lubricants are also able to reduce the friction of coefficient compared to pure Ni-Cr composite. SEM analysis shows the spreading of solid lubricant/s during the sliding test to provide lubrication to both contacting metals.","PeriodicalId":23331,"journal":{"name":"Tribology - Materials, Surfaces & Interfaces","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2020-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/17515831.2020.1777759","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43120104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tribo-test data was recorded each pass over test surfaces showing how friction changes with mechanical action. Trackside environmental monitoring and railhead swabbing was performed to investigate the physical and chemical environment of the railhead. Iron oxides were both synthesized on and deposited on rail steel substrates to simulate ‘wet-rail’ conditions. Powdered oxide layers of magnetite, haematite, goethite and lepidocrocite were deposited on rail steel substrates to investigate individual oxides. Composition was analysed using X-ray diffraction and scanning electron microscopy before testing. Magnetite, Haematite and Lepidocrocite were formed when water alone was applied to the surfaces. Low friction was observed on oxidized sample surfaces only outside high roughness, oxide pitted, areas, but these conditions were shown to be difficult to achieve and transient.","PeriodicalId":23331,"journal":{"name":"Tribology - Materials, Surfaces & Interfaces","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2020-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/17515831.2020.1765611","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43483975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
