Research of erosion resistance of soldered joints with protective coatings

Kashin D.S., Ivanov I.M., Doronin O.N.
Abstract

Presents results of studies of the erosion resistance of soldered joints with various types of coatings. It was established that a coating based on tungsten carbide, applied by the electrospark method, has the greatest positive influence on the erosion resistance of VPr4 solder. At the same time, preliminary machining of the solder surface also increases resistance to the effects of erosion flow. The possibility of using an electrospark coating as an erosion-resistant sublayer for composite protective coatings was shown.

Keywords
erosion-resistant coating, soldered joints, electrospark alloying, solder, erosion resistance.
