A new method for precisely measuring the surface strength of thin films and materials through commissioned analysis and testing. This innovative strength testing method utilizes impact energy, which is not present in conventional tests.
The testing method is a new mechanical property (strength) testing technique that can measure the strength of material surfaces with nanometer-level resolution. It has two innovative features: one is the ability to obtain a "continuous strength distribution from the surface to the interior," and the other is the "visualization of the dual characteristics of materials, such as being hard and brittle." It allows for the easy acquisition of strength distribution in thin films, coatings, and surface treatments, which can be useful for material evaluation and design quality assurance. [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] It measures strength by using the phenomenon of precisely eroding (fracturing) the test specimen with a large number of micro-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. *For more details, please download the catalog or contact us!

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.

Company information
Amid the significant trend of paradigm shifts, through creativity-driven research and development, we aim to propose new surprises—values and technologies, as well as next-level efficiency and quality—to our society, spreading all these surprises to the world and creating a vast network of "monozukuri" (manufacturing) and "kotozukuri" (value creation). We aspire to expand a network of manufacturing that encompasses the world, starting from Nagaoka, a city representing Niigata, a region known for its industrial development.
