On the Applicability of Iron-Based Coatings Against Abrasion and Cavitation Erosion Wear

The cavitation erosion and abrasion resistance of several Fe-based coatings produced by HVAF and HVOF processes were investigated in this research. The ability of these phases to influence ductility and hardness can be crucial in achieving the desired material properties. In addition to precipitates, the effects of martensite and retained austenite phases were investigated by heat treatment, as the ability of these phases to influence ductility and toughness can be important in determining the desired material properties. Experimental and two commercial Fe-based alloys are compared to WC-Co and Cr 3 -NiCr coatings by property mapping.

Cavitation Erosion Behavior of Nb Strengthened Duplex Stainless Steel Surfacing Layer

In this paper, the Nb-containing duplex stainless steel was made using the tungsten inert-gas welding powder surfacing process, and the solution treatment was carried out at various temperatures. The results revealed that, relative to the as-welded 2209 DSS, Nb-containing DSS had higher strength and lower plasticity, which was evident. The cumulative weight losses of the Nb-containing DSSs for 6 h were less than that of the control group in the ultrasonic CE experiment. However, solution therapy caused the Z phase to appear in the Nb-containing DSSs.

Cavitation-Erosion behavior of laser cladded Low-Carbon Cobalt-Based alloys on 17-4PH stainless steel

The electrochemical corrosion test was also investigated to determine the causes of the synergistic effects of cavitation and electrochemical corrosion. The Stellite 728's experimental findings were compared to those of the Stellite 6B and wrought Stellite 6B, which were well-known cavitation-resistant Stellite 628. The experimental findings show that the Co-based alloys have higher cavitation erosion resistance than 17-4PH, and that laser cladded Stellite 728 has improved cavitation resistance in a 3. 5 wt% NaCl solution than laser cladded Stellite 6B and wrought Stellite 6B, owing to the manufacture of significant amounts of Mo-rich intermetallic compound in the alloy.
