Abstract:

The purpose of the work was to define and establish conditions of fretting wear on uncoated, shot-peened Ti-6Al-4V under which conditions fatigue effects may be expected in aircraft gas turbine engine compressor applications. The study was divided into two tasks, each concerning a specific wear phenomenon and resulting fatigue effects. Task 1 involved classic fretting fatigue between bolted surfaces relating to aircraft compressor disc assemblies. Task 2 involved studies of wear simulating that between surfaces of dovetails, in which contact pressure and displacement are related to dynamic loads.
