Wire self-adhesive applying by flame spraying to produce coatings easy to be machined

a. self-adhesive by applying wire flame spraying to produce a coating easy to be machined. b. It comprises an aluminum sheath and a compressed powder core in which a major part is formed by nickel and stainless steel and including a minor portion is composed of aluminum and a metal oxide. The core may contain, by weight, 10 to 90% and preferably about 61% nickel, about 10 to 90% and preferably 30% stainless steel, 1 to 10% and, preferably, 5% aluminum and from 0.25 to 10%, preferably 4% of a metal oxide which may, for example, be cobalt oxide or zirconium, the latter being preferable. c. The invention enables the production on metal parts and an adherent coating easy to be machined, in particular grinding and grinding.
