| Outline of Final Research Achievements |
In order to establish a MSE (micro slurry-jet erosion) evaluation method for surface strength, we investigated following subjects in this study such as production of MSE Tester enable to measure the amount of erosion automatically, analysis of the relationship between surface property and erosion rate (evaluation parameter) of various thin coatings and WC-Co alloy, and analysis of mechanism of erosion (nano or micro scale fracture and damage).
As a result, the strength properties of VC coatings and AlCrSiN gradient coating became clear and also the good relationship between erosion rates of DLC films and hydrogen content were found. In addition, as for WC-Co alloy, we analyzed erosion debris and revealed that failure mode changes depending on the size of the impacted particles. Furthermore, we have shown consideration of damage mechanism and influence factors by numerical simulation. From the above, the usefulness of MSE method became clear.
