ABSTRACT

Tungsten carbide is known for its excellent mechanical properties and is commonly used as a surface coating material for various tools. However, existing coating technologies are hindered by high process costs and poor durability due to the thinness of the coating layers. Therefore, there is a need to reduce costs and develop a unified manufacturing process. In this study, we explore a technique for analyzing and manufacturing tungsten carbide coating samples using a single sintering process with tungsten carbide and stainless steel powder. When these powders are sequentially filled and sintered in a mold, pore regions tend to form at the interface due to the behavior of the cobalt liquid phase, leading to segregation. To address this issue, a nickel powder layer was inserted as an intermediate layer to suppress the cobalt liquid phase behavior. As a result, the formation of pore regions was effectively prevented.
