采用正交实验设计法,选择影响钛合金微动磨损的位移、载荷、频率3个主要因素,设计L16(45)正交表,研究钛合金TC4-DT在不同试验条件下的抗微动性能.以磨损量、摩擦因数为指标研究其微动摩擦磨损特性.结果表明:影响钛合金TC4-DT微动磨损性能的3个因素中,位移、载荷为高度显著影响,频率为显著影响.钛合金TC4-DT的微动磨损为磨粒磨损、粘着磨损和剥层磨损交互作用的结果.
The fretting wear characteristics of TC4-DT alloy were studied using orthogonal design experiment. According to the three major factors that affect the fretting wear of titanium alloy, the anti-fretting properties of TC4-DT alloy by L16 (45) orthogonal table were studied. The fretting friction and wear characteristics were evaluated by the abrasion and friction coefficient. The results show that displacement and load are highly significant factors whereas frequency is significant factor for the fretting wear performance of TC4-DT alloy. The fretting properties of TC4-DT alloy are the results of the interaction of abrasive wear, adhesive wear and peel wear.
