Improving the efficiency of grinding parts from materials with shape memory effect
The features of the intermetallic alloy of nitinol and the problems of its processing, which has unique properties, are considered. The material is poorly amenable to blade processing and well - abrasive, but it is required to evaluate the formation of the bearing capacity of the surface by highly porous characteristics of grinding wheels. A statistical study of the flat grinding of the contact surfaces of nitinol parts in terms of the relative reference part of the plane was carried out. The presence of a relationship between statistical values according to the results of its assessment with the characteristics of the abrasive wheels under study is shown It has been established that nitinol in the austenite state gives a significative of the supporting capacity higher than in the state of martensite. The highly porous characteristic of the wheel has a noticeable, but not favorable, effect on the supporting capacity of the surface. Traces of movement of a wheel form a pseudo-regular relief.
