By the CFD(computational fluid dynamics) software FLUENT, the abrasive flow shape during abrasive flow machining(AFM) was simulated by the Spalart-Allmaras model which is a Mixture turbulent flow model for solid-fluid two phase flow system.

The results strongly indicate that both the abrasive particles and porosity in honing stone have an important effect on the service performance.

The effect of the properties of abrasive particles in slurry, including the morphology and hardness, on the wear resistance of alumina-reinforced yttria-stabilized zirconia polycrystals (3Y-TZP/10wt%Al_2O_3, 10ADZ) was investigated in 5%NaOH slurry containing different abrasive particles using a pin-on-plate tribometer.

The wear properties of alumina reinforced Y-TZP composites in 5%NaOH slurry containing different abrasive particle were investigated using a block-on-block friction and wear test apparatus.

3D measuration and reconstruction technology is introduced in analysis of wear debris.

The evolutions of wear debris characteristics as wear progress in sliding wear process was studied.

This project focused on the issue to establish the evaluation approach of surface features of wear components based on surface characteristics of wear debris.

The design of fractal dimension computing system about the wear particle based on real color;

Study about the fractal characterization of the wear particles boundary;
