Název v původním jazyce
Abrasion resistance of alloy coatings deposited by plasma spraying
Popis výsledku v původním jazyce
Abrasion resistance of a series of plasma deposited alloy coatings was tested. Fe-based alloys (high-alloy Cr- and Cr-Ni-steels, Fe-Al, Fe-Cr-Al, cast iron) and a Ni-Cr alloy were studied. A device for testing slurry (corundum in water) abrasion corresponding to ASTM G75-02 was employed for this purpose. For comparison, two coatings exhibiting extreme abrasion behaviour were measured by the same method: highly abrasion resistant plasma depositedWC-Co and poorly resistant arc sprayed Cr-Ni-steel. To reveal the possible differences between alloy coatings and bulk alloys, the results obtained from plasma deposited high-alloy steel coatings and bulk steels of virtually the same compositions were compared. In addition to the abrasion behaviour, hardness andmicrohardness (i.e. hardness of a single alloy splat) were determined. The observed differences in abrasion resistance of plasma sprayed alloy coatings were relatively small. This also relates to bulk steels.
