Profile I learned material science and strength when I was a Ph.D student, and I worked for several projects corresponding to advanced material processing technologies during my post-doc periods. Through those experience I have several background. Especially I am specialized in surface fabrication by means of abrasive jet technology. This technology is purely “mechanical”, however, I have been researching this subject with multidisciplinary viewpoints, including chemistry, biology and so on.
My research interests covers shot peening, surface modification, tribology, biomedical materials, wet/dry-process coatings, and precision machining. Details of my ongoing projects are given below.
Research Field(Keyword & Summary)
  1. Material transfer during shot peening process and its application for novel surface modification

    When metallic substrates are shot-peened using a metallic shot particle, the peened surfaces are often enriched with the elements from the particle. This was because elements of the shot particle transferred onto the collision crater. I have been interested in this “material transfer” phenomena, and researching to apply them as a novel surface modification technology. Several projects are ongoing to study fundamental mechanism and practical benefits of peening-induced material transfer. Expected fields to apply this research are tribological components, novel jointing technologies, and pretreatment of various coating techniques, etc.

  2. Periodical texturing by means of abrasive jet machining

    Textured surface has been emerging technology since it provides various benefits such as friction reduction, controlled wettability, specific optical properties. My original technique, angled fine particle peening (angled-FPP), can fabricate periodical surface texture by repeated collision of shot particles from shallow angle. Angled-FPP can be conducted by using simple apparatus, and create various texture without masking process. Research aims corresponding to angled-FPP are: to reduce friction coefficient by using appropriate surface texture, to explore surface texture which can prevent adhesion of nanoparticles, and to create plastically generated texture on brittle materials.

  3. Surface texturing aiming to avoid powder adhesion

    Ultra-fine powders easily adhere to the surface of industrial equipments and civil structures and then cause various problems. Anti-adhesion surface modifications are potential technology to overcome the powder-adhesion related problems. I study a novel peening process which can create a specific surface texture which can suppress powder adhesion onto the texture. Recently I try on applying the texturing technique for fabricating nano-scaled texture onto glass surfaces. This process is expected to apply the cover glass of sollar cells; the superfine roughness avoilds attachment of PM2.5s onto the surface while transparency of the glass was maintained.

  4. Eco-friendly electrodeposition

    Electrodeposition of chromium plating has been widely employed for various machine components. However , the impact of hexivarent chromium, which is contained in typical chromium plating baths, to the enviroment and health of workers in plating factories becomes serious concern. I am working on proposing a trivalent chromium plating as a potential alternative to the conventional hexavarent chromium plating. Coatings deposited from trivalent chromium bath are investigated from the viewpoints such as wear resistance, interfacial adhesion, and corrosion resistance.
