Durability of the Layers Deposed with Metal – Ceramic Powders Type CR3 C2 –NICR and High Speed Flame (HVOF)

Abstract

The durability of the reconditioned or preventively covered with powders type Cr3 C2 –NiCr product may outrun the performances of the original product and (the original specification, too). Due to the deposit of these layers with superior properties of the basic material, there may be maintained also at a maximum level maintenance expenses during a long period of time. In the present study there are studied the effects of the main high speed flame thermal spraying parameters on some properties of the layers deposed with powder type Cr3 C2 –NiCr, with the help of the orthogonal regression method and also the correlation of the deposits’ properties.
