Quantitative assessment of the thermal role and wear characteristics of multi-layer coatings in cutting tools is approached through the analysis of mechanical contact problem at the tool-chip interface and the constriction resistance phenomenon. The micro-contact configuration on the surface asperity level and the macro-contact configuration (contact pressure distribution and the size of the adhesion and […]

Nickel based alloys manufactured via powder metallurgy (PM) are the next generation of materials that offer great service performance and increased efficiency of gas turbine engines. This class of material is characterized by their poor machinability. Additionally, limited information is known about the integrity of machined surfaces; thus limiting its acceptance by the industry. This […]
