ABSTRACT:
The disclosure relates to rotary machinery, including a wear ring seal member stationarily mounted in a holding member which extends generally coaxially about a rotatable cylindrical member in substantially sealing relationship with the surface of the rotatable member, the rotatable member being made of carbon steel. The improvement resides in providing the surface of the rotatable carbon steel member in sealing relationship with the ring seal with a fused alloy coating metallurgically bonded thereto, the coating being formed of a heat and corrosion resistant welding alloy composition containing about 10% to 30% by weight chromium and the balance at least about 60% nickel, such that the carbon steel member is protected against oxidation and ignition due to overheating.
