In order to perform an in-depth study into the mechanisms that govern the formation of this surface, all factors involved in the machining process must be ascertained. The resulting surface after turning (real surface) is studied as the superposition of multiple surfaces. A first surface, (tool surface), is generated from the geometry of the tool and machining parameters. A second surface (vibration surface) is generated from the vibration of the tool. Finally, a third surface (other-factors surface) is taken as the joint result of fracture of material, elastic recoveries, plastic deformations, hardness, kinematic, deposits and/or adhesions of material and/or tool wear. The comparison of these four surfaces enables this objective to be reached. A new parameter denominated dispersion is defined. Principal component analysis (PCA) is used in the definition of this parameter.","PeriodicalId":14460,"journal":{"name":"International Journal of Surface Science and Engineering","volume":"12 1","pages":"77"},"PeriodicalIF":0.8,"publicationDate":"2018-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48838239","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 this case study, static load capacity of the ball bearings was shown to be 31% lower than that specified by ISO and ANSI/ABMA bearing standards; 2) characterise machined surfaces with 2D and 3D parameters, with the goal of producing optimal surface finish on orthotic knee joints used by Cerebral Palsy patients.

Frictional properties of the deep-drawing quality steel sheets were investigated using the strip drawing test under both dry and lubricated conditions. An increase in the plastic deformation of sheets in the range of true strain between 0 to 0.28 caused an increase in the value of amplitude roughness parameters Ra, Rp, Rt, measured along the rolling direction of the sheet metal and perpendicular to this direction. The character of frictional phenomena of the deformed sheets is a complex function of sheet directional topography, formed by pre-straining and strain-hardening phenomena. It was also found that owing to the strain-hardening phenomenon the micro-hardness of the sheet increased with the sheet deformation. However, this relation was near linear.","PeriodicalId":14460,"journal":{"name":"International Journal of Surface Science and Engineering","volume":"12 1","pages":"119"},"PeriodicalIF":0.8,"publicationDate":"2018-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44826684","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 laser treated surfaces presented a combination of oxides and wear behaviour distinctly superior to the bare surface. The coefficients of friction (COF) of the lasered surfaces were approximately half of the bare condition.

Three laser parameters (laser power, beam diameter and laser scan speed) were used to ascertain the proper operating condition for this laser process.

The DLC/DLC contact showed approximately 60% lower wear when tested with additivated oil compared to that of base oil and this result was 66% in steel/DLC contact. Friction coefficient in DLC/DLC contact was lower than in steel/DLC contact under both oils. But however, both contacts showed slightly higher friction coefficient under additivated oil compared to that of base oil. In steel/DLC, the thermo-chemical reaction between carbon and iron and/or the fusion of the transferred particles were prevented by additives which were present under base oil. The fracture found on DLC surface in steel/DLC contact under additivated oil indicates that the tribolayer formed on the steel surface would be of brittle nature. The passivation of surfaces in DLC/DLC contact by additives prevented the damage which was observed under base oil.","PeriodicalId":14460,"journal":{"name":"International Journal of Surface Science and Engineering","volume":"12 1","pages":"60"},"PeriodicalIF":0.8,"publicationDate":"2018-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44799007","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 research work aims to investigate the influence of chromium (Cr) on wear characteristics of powder metallurgy (P/M) plain carbon steel (Fe-0.5%C) and to find optimal parameters for minimum wear loss and frictional coefficient of the P/M alloy steels. The sintered-forged plain carbon steel and with addition of 1% and 2%Cr P/M alloy steels were made into cylindrical pins to conduct wear tests as per the standard. The Design Expert (DE) software was used for conducting the dry sliding wear tests. Addition of Cr reduces the mass loss due to the formation of chromium carbides embedded in the ferrite grain matrix in the microstructure. The optimum working parameters found for the minimum mass loss and coefficient of friction from the Taguchi-grey relational analysis are 50 N load and 113.5 rpm speed irrespective of the alloy steels.","PeriodicalId":14460,"journal":{"name":"International Journal of Surface Science and Engineering","volume":"11 1","pages":"381"},"PeriodicalIF":0.8,"publicationDate":"2017-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48744772","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}
