Study of coatings from refractory carbide powders on some steel rods prepared by using equipment with a rotating electric arc

A successful attempt has been made to use recently developed equipment, which can produce a rotating electric arc, in the preparation of coatings made from refractory carbide powders on certain types of steel. Although some weak points were observed in the applied procedure of coating steel rods, it is still worthwhile to continue investigations in order to improve our coating technique and thus to obtain coating materials with improved properties in comparison with uncoated materials. In particular, it should be noted that this simple method of coating is applicable even to items of very large dimensions.
