Abstract

A method for formation of hardfacings on an article comprises producing, by powder metallurgy or additive manufacturing, an article having a discontinuous surface. The article is exposed to impact items and to tungsten carbide particles, provided as tungsten carbide particles comprised in the impact items and/or tungsten particles provided directly in a process fluid as a dispersion. At least 80% of the tungsten carbide particles have particle sizes within the range of 0.1-5 μm. The impact items are bodies with an average diameter within the range of 0.1 to 10 mm. A velocity difference is created between the surfaces and the impact items, causing impacts between the impact items and the surfaces, giving polishing, induction of compressive stress, and/or densification of the surface. Tungsten carbide particles are embedded, hammering the tungsten carbide particles into the article by use of the energy of the impacts.
