BASIC PRINCIPLES OF ALUMINUM DEPOSITION ON A HARD ALLOY IN PRODUCING OXIDE COATING
RESUMO
High temperatures have an adverse effect on the physical and chemical characteristics of tools. This problem can be solved by using Al2O3-based composite coatings, produced by the micro-arc oxidation method; these coatings have the tool resistance factor two times higher than that of the hard alloy plates with a traditional coating. The opportunity for the industrial implementation of the technology of applying Al2O3-based coatings on the cutting tools is discussed. The composition of coatings and their deposition on the substrate under various technological conditions are analyzed at the micro- and nanoscale levels. The relationships between the micro-nanostructure parameters and the coating operation efficiency are evaluated.
