Process for the effective production of very wear-resistant layers in the thickness range of 0.2 to approx. 3 mm by way of inductively supported surface layer modification. It can be used particularly advantageously for the protection of components of hardenable steels and cast iron with abrasive, corrosive, high-temperature corrosive or mineral sliding wear loading. With the process according to the invention a local two-stage inductive short-time preheating takes place directly before the surface layer coating. Due to the invention it is possible to coat even hardenable steels or other materials difficult to coat without cracking. Furthermore, even harder coating materials susceptible to cracking which provide better wear-resistances can be used. In addition, process speeds and surface coating performances can be achieved that are higher by a factor of 10 compared with conventional laser build-up welding. This abstract is neither intended to define the invention disclosed in this specification nor intended to limit, in any manner, the scope of the invention.
