An analysis of structures occurring in weld deposit of steel S235JR+N with tungsten carbide particles and martensitic matrix

Abstract

Protective layers include special weld deposits, utilizing e.g. ferrous, nickel or cobalt matrices in combination with tungsten carbide particles, which according to their properties belong among so-called composite materials, and which have slowly replaced conventional components produced from tool steels. A weld deposit with an iron-based matrix (Megafil A864M) was used, with tungsten carbide particles on steel S235JR+N. The high-level hardness of tungsten carbides together with a tough matrix allows achieving high resistance to different types of wear. This resistance significantly increases the lifetime of machine components and thus it reduces the costs of companies needed for repairs or the replacements of machine parts.
