This study investigated the effects of deposition techniques on the microstructural and tribological properties of Ti/TiN/TiCN/TiAlN multilayer coatings onto a Custom 450 steel substrate. The coatings were produced using cathodic arc physical vapor deposition (CAPVD) and plasma-assisted chemical vapor deposition (PACVD). The microstructural of the coatings was evaluated using (SEM), and phase f...

Usually, the calculation for bodies with laminated coatings is connected with formulating and solving appropriate problems of mathematical physics for multilayer systems, which are cumbersome and ineffective for practical purposes and are typically used as standards in elaborating approximate methods. This paper suggests an approach essentially simplifying solving the problems of the determinat...

Advancement in vacuum technologies and vapor deposition processes during last decades has led to the introduction of many modern coatings on metal cutting tools. Even in such an advanced vacuum coating techniques, the failure is not due to the wear of the coating but rather due to the lack of coating adhesion to the substrate. In this work, the coating adhesion test results were performed which...

A variety of microscopic techniques are employed to characterize fluence limiting defects in hafniakilica multilayer coatings manufactured for the National Ignition Facility. This work was performed under the auspices of the U.S. DOE by LLNL under contract No. W-7405-Eng-48. Characterization of fluence limiting defects in hafniakilica multilayer coatings manufactured for the National Ignition F...

Abstract The paper presents new results on the application of microplasma spraying (MPS) for manufacturing electric heating elements (EHEs) consisting a St3 steel plate (the substrate) with sprayed electrically insulating Al 2 O 3 sublayer (400±50 μm thick) and TiO tracks (4 mm width; 150±50 thickness). Measurements temperature multilayer coating thermal imager enabled determination distributio...
