Study on the Wear Mechanism of Brazed Diamond Grains
Plenty of studies on wear mechanism of diamond grains show that the specific failure form of single diamond grit has a close relationship with its load. Monolayer diamond grinding wheels and samples for shearing test are prepared by a high frequency induction brazing technique in this paper. The normal abrasion mechanism of diamond grains has been found through the comparison between the single grain tangential load during grinding and the shearing failure-load of the single grit of the test samples. The result shows that the dynamic strength of diamond grains is relative to the static strength after being brazed. Most of the grains are micro-broken during grinding, and only a few of them are pulled-out or broken-off.
