Colmonoy 69 HV Nickel Base Powder Ni-69HV Powder Ball Valves Centrifugal Pump Parts

Product Description

Colmonoy 69HV is designed for use in HVOF Systems and does not require fusing.
Colmonoy 69HV is used for ball valves, centrifugal pump parts, heat exchanger tubes and other nonpoint loading applications. The coating is well suited for applications requiring abrasion and corrosion resistance, particularly in the as-sprayed condition when fusing is not possible. The coatings are also used to protect against particle erosion up to 1500°F(815°C).

Colmonoy 69HV cannot be hardened by fusing. A Metallurgical bond can be achieved, and coating integrity can be increased by torch, induction or furnace fusing. The fusing temperature is approximately 1890°F (1030°C). Coatings of Colmonoy 69HV can be ground with silicon carbide or machined with CBN or carbide tooling.

Colmonoy 69HV can be utilized as a chromium plating replacement. Though not as hard (58-63HRC), the coating is more dense (≥98%) and far less prone to cracking.

HRC: 58-63
Common Name: Colmonoy 69HV

Surface Preparation

Surface should be clean, white metal, with no oxides (rust), dirt, grease, or oil on the
surface to be coated. Note: It is best not to handle surfaces after cleaning.
Recommended method of preparation is, to grit blast with 24 mesh aluminum oxide,
rough grind, or rough machine in a lathe.
