A method for the production of wear-resistant borierschichten on metallic objects, as well as metal article with a wear resistant borierschicht

摘要

Tough, deformable, wear-resistant borate coatings are applied to metal articles by contacting a powdered formulation contg. B with at least one surface of the metal article and then heating. The novelty is that outer layer remelting of the metal article surface is performed using a high-energy heating source, causing boron or boron carbide components of the borating powder to be incorporated in the remelt layer so that on cooling, a B-contg., feathered lamella structure is formed. ADVANTAGE - Reduced boration times and preselection of coating hardness. Small deformations of the borated layer do not lead to cracking and the process is easily incorporated into a production line
