Abstract
Plasma spray powders of molybdenum particles containing at least 0.5 weight percent oxygen and obtained by reacting molybdenum particles with oxygen or oxides in a plasma, form plasma spray coatings exhibiting hardnesses comparable to flame sprayed coatings formed from molybdenum wire and plasma coatings of molybdenum powder containing hardening alloy powders. Such oxygen rich molybdenum powders may be used to form wear resistant coatings, such as for piston rings.
