Abstract
A method is provided of creating a pipe connector including a first connector member and a second connector member, said connector members being adapted to be connected and disconnected multiple times, the method comprising: a) providing at least one of the connector members with a contact surface; b) depositing particles of a galling resistant metal on each said contact surface; c) at least partially melting the particles of the galling resistant metal by subjecting the particles to a quantity of heat; and d) allowing the molten galling resistant metal to solidify thereby forming a galling resistant metal coating which is metallurgically bonded to the contact surface. The heat may be provided in the form of radiant energy, using a laser beam.
