The ultrasonic vibratory test was carried out to evaluate the cavitation erosion/corrosion resistance of welded-deposited austenitic stainless steel/E308L-17. Three layers of the E308L-17 electrode were deposited onto AISI 1040 substrate utilizing Shielded Metal Arc Welding (SMAW) process. The eroded surfaces of the E308L welded deposit/coating and AISI 1040 substrate steel have been analyzed by evaluating surface topography, as well as scanning electron microscope (SEM) micrographs. In addition, the cumulative weight loss and erosion rate curves were attained to evaluate the cavitation resistance of the tested materials. The cavitation results showed that the E308L-17 deposited stainless steel has lost about 15 mg as a cumulative weight, while the loss of AISI 1040 substrate was about 123 mg. This is equal to 0.12% and 1.0% of the original test specimen weight for the E308L-17 and AISI 1040, respectively. Consequently, E308L-17 austenitic stainless steel can be effectively used as a protective material for surfaces exposed to cavitation wear, since the AISI 1040 substrate has been enhanced by 8 times using E308L stainless steel.

Abstract Colmonoy No. 43HV comprises a nickel-base alloy recommended for hard surfacing parts to resist wear, corrosion, heat, and galling. Deposits that have moderate hardness have increased ductility and slightly less resistance to abrasion than Colmonoy 53HV. Deposits can be finished by grinding or machined with carbide tooling. Colmonoy No. 43HV is supplied as an atomized powder specially sized for application with high-velocity oxygen fuel (HVOF) systems. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on corrosion resistance and surface qualities as well as heat treating and surface treatment. Filing Code: Ni-664. Producer or source: Wall Colmonoy Corporation.
