The improvement of steel properties using Al2O3 coatings deposited by plasma spraying

Abstract

It is well-know that the numerous functions of use of materials can be realized at a high level of performance by using plasma jet coatings, with the reduction of the consumption of important strategic metals. These are determined by the excellent resilience to extreme temperatures, corrosion and wear of the coatings. This paper aims to characterize coating layers based on Al2O3 realized by plasma jet spray by examining its hardness, thermal shock resistance, traction resistance.
