In this paper we tried to present a qualitative correlation,based on extensive experimental determinations between the value and the evolution of the friction coefficient,wear,and contact temperature,in the case of linear dry contact,for thermoplastic material reinforced with short glass fibers(SGF)and various steel *** aim was to highlight the evolution of the wear process depending on the evolution of the friction *** a result,it was possible to graphically illustrate the evolution of the friction coefficient and the change of the wear process,emphasizing the abrasive,adhesive and corrosive *** evolution of the plastic material transfer function of the contact temperature,namely of the power lost by friction(product between the contact pressure and sliding speed,p and v)was aimed and it was *** has been demonstrated that in the case of a 30%SGF content it can reach and even exceed contact temperatures very close to the flow limit of the plastic *** tried,believing successfully,the graphic illustration of the evolution of the steel surface wear and of the contact temperature,depending on the friction *** influence of the normal load and sliding speed was evaluated in detail,but also the influence of the metallic surface roughness on the friction coefficient was discussed.

Wear and Contact Temperature on Steel Surface in Linear Dry Friction Contact with Polimers with SGF

引用

Journal of Mechanics Engineering and Automation 2015年第10期5卷 554-566页

作者： Dorin Rus Lucian Capitanu Mechanical Department Technical University of Civil Engineering Bucharest 050153 Romania Tribology Department Institute of Solid Mechanics of the Romanian Bucharest 010141 Romania

In this paper, we tried to present a qualitative correlation, based on extensive experimental trials between the value and the evolution of the friction coefficient, wear and contact temperature in the case of linear dry contact, thermoplastic material reinforced with SGF （short glass fibres） and various steel surfaces. We tried, believing successfully, the graphic illustration of the evolution of the steel surface wear and of the contact temperature, depending on the friction coefficient. It was analyzed in detail the influence of the normal load and sliding speed, but also of the metallic surface roughness on the friction coefficient.
