Method of applying corrosion, oxidation and/or wear-resistant coatings

An article having a surface with a coating having at least one of corrosion-resistant, oxidation-resistant or wear-resistant properties, the coating produced by the process comprising the steps of;

• (a) providing a powder of at least one of a ceramic compound of the general formula (I);
• M2X1Z1 (I)
• wherein M is at least one transition metal, X is an element selected from the group consisting of Si, Al, Ge, Pb, Sn, Ga, P, S, In, As, Tl and Cd, and Z is a non-metal selected from the group consisting of carbon and nitrogen;
• and a ceramic compound of the general formula (II);
• M3X1Z2 (II)
• wherein M is at least one transition metal, X is at least one of Al, Ge, and Si, and Z is at least one of carbon and nitrogen;
• and
• (b) thermal spraying the powder of the at least one compound onto the surface.

A method of coating a surface comprising the steps of:

• (a) providing a powder of at least one of a ceramic compound of the general formula (I):
• M2X1Z1 (I)
• wherein M is at least one transition metal, X is an element selected from the group consisting of Si, Al, Ge, Pb, Sn, Ga, P, S, In, As, Tl and Cd, and Z is a non-metal selected from the group consisting of carbon and nitrogen;
• and a ceramic compound of the general formula (II):
• M3X1Z2 (II)
• wherein M is at least one transition metal, X is at least one of Al, Ge, and Si, and Z is at least one of carbon and nitrogen;
• and
• (b) thermal spraying the powder of the at least one compound onto the surface;
• whereby a coating having at least one of corrosion-resistant, oxidation-resistant or wear-resistant properties, results on the surface.
