Babbitt Alloy Tribological Behavior with Varied Coating Thickness and Roughness

Pin-on-disk tribological tests evaluate the friction and wear of a Babbitt alloy coating in contact with ABNT 1045 steel. The study, authored by Rafael Martins Ribeiro, varied coating thickness in three levels from 0.45 ± 0.07 mm to 1.08 ± 0.17 mm and roughness from 0.43 ± 0.03 μm to 1.29 ± 0.20 μm. Results show the friction coefficient increased from 0.05 ± 0.02 to 0.46 ± 0.06 for specific parameter combinations.

Use Cases

• Modeling friction coefficient based on coating thickness and roughness parameters described in the study.
• Predicting wear rates of Babbitt-steel contacts using the experimental test results.
• Optimizing bearing surface parameters for reduced friction using the described pin-on-disk test methodology.
• Analyzing the interaction between coating thickness and surface roughness on tribological performance.

Strengths

• Experimental results include specific numerical ranges for friction coefficient (0.05 to 0.46) and wear.
• Key parameters (coating thickness and roughness) were varied across three defined levels each.
• The description provides detailed test conditions, including the use of ABNT 1045 steel pins and Babbitt-coated specimens.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
