MoSe2/石墨烯-不锈钢自润滑材料的减摩机理
Friction Reduction Mechanism of MoSe2/Graphene-Stainless Steel Self-lubricating Materials
摘要
Abstract
In order to overcome the shortcomings of high friction coefficient and easy wear of stainless steel friction pair parts,based on the through-hole characteristics of powder metallurgy stainless steel porous matrix and the super sliding effect of heterojunction nano lubricants,a two-step preparation process of vacuum impregnation and hydrothermal synthesis were used to preduce MoSe2/graphene-stainless steel self-lubricating materials.The tribological properties and friction reduction mechanism of the composites were studied.The results indicate that the MoSe2/graphene lubricants in the matrix pores form a uniform lubricating film on the friction surfaces under the dragging effect dur-ing the friction processes,and significantly reduce the friction coefficient and wear rate of the friction pairs.At room temperature,load of 40 N,and speed of 100 r/min,the friction coefficient drops to 0.106,and the wear rate drops to 6.45 × 10-5 m3/(N·m).Compared with the stainless steel matrix,the friction coefficient and wear rate are reduced by 86％and 93％respectively.关键词
