| Abstract | Purpose: It was explored fretting resistance titanic alloy VT3-1 (Ti-Al6-Cr2-Mo2,5) after low temperature ionic nitriding in unhydrogen environment. Design/methodology/approach: Small amplitude fretting was initiated by the dynamic contact of ball and flat in the regime of the partial slip on edge of spot of contact. A method differs by simplicity and express determination of fretting resistance, namely areas of destruction by action of fretting for part nominally fixed contact - how the functions of cycles of loading. Findings: As a result of fretting the central region of sticking decreasing, and the edge of areas of fretting are increasing. Practical implications: The method of initiation of small amplitude fretting within bounds of preliminary displacement is offered. On the offered method the destruction of titanic alloys is explored at fretting and influencing of ionic nitriding on fretting. By a computation method the work of forces of friction in the area of wear, which in 5..6 times is less for nitriding titanic alloys, is appraised. Originality/value: A method allows defining reactionary power of nitriding layers for small amplitude fretting. |
