Abstract
The effects of cladding microstructure in new developmental alloys for both cladding and casing wear in block-on-ring test configuration was investigated. The block-on-ring test configuration is simple to use and can help in evaluating the friction and wear of drill-shaft cladding alloys against a casing alloy in slurry-lubricated conditions and the results from this test produced more quantitative wear measurements than pin-on-disk tests on similar materials. A very good correlation between friction and wear of both the cladding and casing materials in slurry-lubricated conditions was established by using block-on-ring test and also a good relation between cladding wear and casing wear was observed. The composition of the claddings was also important as a fine, uniform cladding microstructure which produced lower friction and wear than coarser microstructures. The results also suggest that selection of materials can influence sliding friction between cladding and casing materials.
