Abstract
(EN)
For forming a coating exhibiting excellent abrasion resistance over a temperature range from low temperature to high temperature, there is provided a method comprising the steps of preparing a metal powder containing a component capable of exhibiting lubricity upon oxidation thereof; oxidizing the metal powder so that the amount of oxygen contained in the metal powder is increased from 6 wt.% to 14 wt.%; and melting or semi-melting the metal powder so as to form on a treatment object a coating having such a structure that in a unit area of molten or semi-molten state, there are distributed regions of 3 wt.% or less oxygen content and regions of 8 wt.% or more oxygen content, the content of oxygen as a whole after the melting or semi-melting in the coating ranging from 5 wt.% to 9 wt.%.

Selon la présente invention et afin de former un revêtement exhibant une excellente résistance à l'abrasion sur une gamme de température allant d'une basse température à une température élevée, on propose un procédé comprenant les étapes consistant à préparer une poudre métallique contenant un composant capable de présenter un certain pouvoir lubrifiant après son oxydation; oxyder la poudre métallique de sorte que la quantité d'oxygène contenue dans la poudre métallique soit augmentée de 6 % en poids à 14 % en poids; et effectuer une fusion ou semi-fusion de la poudre métallique afin de former sur un objet à traiter un revêtement ayant une telle structure que sur une unité de surface à l'état fondu ou semi-fondu, il y ait une distribution de régions de teneur en oxygène inférieure ou égale à 3 % en poids et de régions de teneur en oxygène inférieure ou égale à 8 % en poids, la teneur en oxygène dans son ensemble après la fusion ou semi-fusion dans le revêtement étant dans la gamme de 5 % en poids à 9 % en poids.
