Abstract: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.
Key words: TC4-DT alloy; orthogonal design experiment; fretting wear property
