Reciprocating piston pump surface treatment process

Reciprocating piston pump surface treatment process

A process for treating rods and cylinders for use in reciprocating piston pumps is provided which yields a substantial increase in wear over the chrome coatings of the prior art. A base material of stainless steel 17-4ph is heat treated in the range generally from H-900 to H-1150. Once the material...

Zusammenfassung:A process for treating rods and cylinders for use in reciprocating piston pumps is provided which yields a substantial increase in wear over the chrome coatings of the prior art. A base material of stainless steel 17-4ph is heat treated in the range generally from H-900 to H-1150. Once the material is pretempered, an ion nitriding process is applied. With this process, the hardness can be increased from the standard 17-4 hardness of RC-44 max to a desired hardness of RC-65 to 75.
