Microhardness and Structure Distribution over the Layer of a High-Hardness Heat-Resitant Alloy Formed by Multi-Layer Plasma Surfacing in a Nitrogen Medium

Microhardness and Structure Distribution over the Layer of a High-Hardness Heat-Resitant Alloy Formed by Multi-Layer Plasma Surfacing in a Nitrogen Medium

The distributions of microhardness, chemical composition and structure over the thickness and surface of a layer formed from heat resistant steel (R2M8Y Grade) by plasma surfacing in a protective-alloying nitrogen medium are studied. It is found out that the surfacing technology and the surface-allo...

Description
Summary:The distributions of microhardness, chemical composition and structure over the thickness and surface of a layer formed from heat resistant steel (R2M8Y Grade) by plasma surfacing in a protective-alloying nitrogen medium are studied. It is found out that the surfacing technology and the surface-alloyed material allow forming a high-quality alloy without any cracks, pores, slag inclusions and macro- and microstructure defects. It is determined that the surface-alloyed layer consists of pearlite grains, with carbonitrides (Ме 6 NC and AlN) based on iron, tungsten, chromium, molybdenum and aluminum distributed along the grain boundaries and intersections.
