Specific Wear Rate Behaviour of Sol-Gel Treated Aluminium Alloys for Bearing Application

摘要

In this work, the suitability of aluminium A390 for bearing application is analyzed by having specific wear rate as the measure. A380 is better known for its application as aluminium bearing material but it is little more costlier than A390. Therefore the ways in which A390 can be improved in properties like A380 is worked out in this work and sol-gel treatment technology associated with dip coating is utilized as the surface treatment technique. Specific Wear Rate analysis is done for these materials and the specific wear rate is found out as a means of comparing A390 with A380. In terms of specific wear rate, it is found that A390 hardened to 55 HRC has equivalent properties to A380 and cost effective.
