[Contract Analysis and Testing Examples] Life Design Starts with Accurate Measurement of Degradation Level

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 (destroying) the test specimen by projecting a large number of micro-particles. As a result, it has enabled the measurement of strength 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 the data measured for the erosion marks for each projection. 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. *Various testing examples of different materials are currently available.
