What is MSE testing in contract analysis and contract testing?

basic information

**Purpose of Development** The MSE test is a technology developed to measure the precise mechanical properties (strength domain) of material surfaces, originating from a collaboration between industry and academia with Fukui University. **Technology** Strength is measured using the phenomenon of precisely eroding (fracturing) the test specimen by projecting a large number of fine particles. As a result, it enables strength measurement at various depths while eroding from the surface, creating a new effect of obtaining a continuous strength distribution from the surface to the interior. **Information Obtained** 1. **Erosion Profile Progress Chart** A visualization of the changes in depth direction by overlaying data measured for each projection of the erosion marks. 2. **Erosion Progress Graph** A graph showing the relationship between the cumulative particle amount projected and depth, calculated from the shape profile of the erosion marks. 3. **Erosion Rate Distribution Graph** A graph that provides nearly continuous information on the erosion rate (strength) in the depth direction. 4. **MSE Map** Information created to quantify the strength of materials in terms of Young's modulus mode and brittle mode for comparative analysis and to confirm development trends.
