Abstract: An apparatus and method for metalizing the surface of metal bodies, such as bars, rods and tubes is providing using a substantially enclosed chamber in which the metalizing is caused to occur. An elongated body to be metalized is moved axially into the chamber through an entrance opening while the body is simultaneously rotated, and then passes through a first induction heating coil to pre-heat a portion of the body surface to a selected pre-heat temperature. The pre-heated portion is then advanced past the pre-heating coil to a point where it is subjected to, and bathed by, a flowing stream of metalizing powder entrained within a heated non-oxidizing gas, such as nitrogen, with the flowing stream directed against the pre-heated body portion so that the entrained metalizing powder impinges against and clings to and covers the entire surface of the pre-heated portion.

Abstract: An apparatus and method for metalizing the interior of pipes or tubes is disclosed. The base metal pipe or tube to be internally metalized is moved axially while simultaneously being rotated at a relatively high rpm. A first pre-heat means, preferably an induction heating means, heats a portion of the pipe and its interior to a first elevated temperature, and particles of the metalizing material are deposited into the interior of the pipe to be heated to said first elevated temperature. The rotation of the pipe distributes the fluidized particles into laminae which, under the further influence of centrifugal forces, automatically distributes the semi-fluidized particles effectively. The fluidized metalizing material is bonded together and to the body substrate by application of a second induction heat at a higher heat level or temperature at which bonding occurs between the laminae of metalizing material and between the metalizing material and the base material of the tube or pipe.
