چکیده
ABSTRACT Surface condition of powder details on the different stages of producing of joining elements is the important factor that influences on the choice of technological conditions of operations and end-use properties and running ability of product. Generally, the roughness, porosity and microstructure determine the surface condition. The results of investigation of surfaces of iron-copper details after compacting, sintering and infiltration are offered. The influence of the technological process on the surface conditions was evaluated by comparison of the average 2D and 3D roughness parameters of iron-copper details after compacting, sintering and infiltration. The present surface roughness research is based on machine parts surface cross section profile analysis. However, in practical applications machine parts surface roughness behaves as a 3D object. Therefore, the “Taylor Hobson Ltd” 3D measurement system has been used. The analysis of the influence of the technological process on the surface roughness parameters is given.
