[Contract Analysis and Testing Examples] Life Design Starts with Accurate Measurement of Degradation Level
Manufacturing is greatly restricted by the sustainable international goals of the SDGs on Earth. We introduce MSE tests that are useful for material and process development.
The SDGs demand technological advancements aimed at reducing energy consumption, lightweighting, minimizing environmental impact, and extending lifespan in manufacturing. In materials, this translates to increased strength, enhanced functionality, and reduced manufacturing costs, necessitating boundary design and stable manufacturing technologies. This requires extensive trial and error and testing to accelerate development speed, making future IoT integration using AI essential. To create the necessary materials database (DB), it is crucial to have technology that accurately measures degradation lifespan based on material characteristics and aging. Future materials will involve not only material development but also multilayer and composite development. We have developed the MSE testing method as a means to quantify and compare the mechanical properties of a wide range of materials. **What can be done with MSE testing:** - Compare ceramics, metals, resins, and rubber materials on the same scale. - Visualize characteristics in hardness (Young's modulus) mode and toughness (brittleness) mode. - Obtain continuous distribution data from the surface to the interior of thin films and multilayer films. - Apply it to precisely test the degree of decline in mechanical properties due to material degradation. Please utilize this for high-speed screening of various material development processes and for creating a database of material strength.

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. Please refer to the catalog for more information.
