This company's tungsten carbide coatings are designed for maximum wear protection, whether the source of the wear is abrasion, erosion, corrosion, impact, or a combination of these elements
This company's tungsten carbide coatings are designed for maximum wear protection, whether the source of the wear is abrasion, erosion, corrosion, impact, or a combination of these elements. The selection criteria for application is based on requirements and the manufacturer's engineer evaluate each substrate and its proposed operating environment to choose the best formulation.
The dense coating can be applied to most surfaces even if the shape is complex, and a thinner layer of this company's coatings may be used instead of a thick layer of other materials due to their density (0.397- to 0.441-lb/in.³). The manufacturer states that, in some instances, 0.060-in. of their tungsten carbide can wear as well as or better than 0.376-in. of weld overlay, or 3.000-in. of hardened tool steel.
The manufacturer applies the coatings using proprietary technology using the formation of a flexible sheet of highly loaded tungsten carbide particles held in a fibrous PTFE lattice. Infiltration brazing is used to ensure a high bond strength and a uniform, densely packed layer of the coating, which is encapsulated in a braze matrix chosen for its ability to withstand corrosion and absorb the shock impact. Infiltration brazing results in bond strengths between coating and substrate that are often in excess of 70,000 psi, according to the manufacturer.
