A case study on the wear mechanism and stress evolution of graphite plugged bronze wear plate from the field trial

Publication Name

Engineering Failure Analysis


Graphite plugged bronze has been primarily applied as the self-lubricating part in the tough oilless conditions, and understanding the detailed wear characteristics and the contacting stress evolution of graphite plugged bronze was important to improve its design for the in-service reliability. This study investigated the wear characteristics and contacting stress of graphite plugged bronze sliding plate from the field trial by means of the multiple topographic characterizations and computational analysis. The results revealed that abrasive wear and adhesive wear predominated on the contacting surface of graphite plugged bronze plate, accompanied by the localized fatigue and erosion. Computational simulation well illustrated the increasingly accumulated stress at the boundary between bronze and graphite as referenced with the stress evolution of bronze matrix and graphite plug, which was considered to be the leading cause of aggravated wear over time. Finding from this study provided the primary wear features of graphite plugged bronze component, which had potential application for the further optimization of the structural restoration and tribological issues of graphite plugged bronze.
