Intercommunication of surface machine parts parameters with their optical characteristics

It is experimentally found out that among the existing methods of mechanical treatment fine sharpening with diamond tool, diamond polishing and abrasive treatment methods are most efficient from the point of view of formation light reflect-ing surfaces of parts, made of aluminum alloys. These methods ensure the lowest values of relation between the parameters of surface roughness Ra /Rmax and the highest value of the criterion of surface roughness F and coefficient of surface reflection. For the control of the physical and chemical state of the treated surfaces it was recommended to utilize the method of estimation of work of electrons work function. Correlation of methods of treatment, roughness of the treated surfaces and their physical and chemical state, was established in the work with optical descriptions of surfaces)
