Additive Brazing for New Part Production, Remanufacturing and Wear Protection
Timo Kolberg, Gon Jung, Dr. Ino J. Rass EUROMAT GmbH, Baesweiler-Germany
Additive soldering is a thermal process, which is carried out without flux in vacuum, under inert gas or atmospherically with solders in powder, slurry or tape form. In this process, two or more component parts are not bonded together but coated with solderable materials by diffusion. Depending on the application, the hardness of the coatings can be flexibly adjusted. The areas of application are remanufacturing, wear protection and new part production and can therefore deliver resource-saving products. The coatings are very dense, abrasion-resistant, crack-free and therefore also very suitable as corrosion protection, even at high temperatures. Unlike cladding, the brazed coatings are relatively smooth and often do not need to be reworked or ground. 2D and 3D geometries can be coated both internally and externally. The presentation will provide an overview of selected processes, materials and applications and an outlook on developments in the field of additive soldering.
