Abstract

A powdery material is prepared by atomization from a molten alloy having the following composition in weight percent: chromium: 10-30; aluminium: 1-25; carbon: less than 0.5; nickel: less than 10; iron: the balance, with a cooling speed at least equal to 400.degree. C./sec., for heat spraying having a grain size comprised between -150 and +27 microns of which the specific area is higher than 500 cm.sup.2 /g. Said material enables to form on a metal substrate a self-adhesive layer having a resistance to pulling by traction which is higher than 20 N/mm.sup.2.
