“…Films deposited on substrate by dynamic ion mixing have an extremely high adhesive strength sustained by a comparably broad intermixed layer between substrate and film. TiN coating by this process can prolong the lifetimes of drills and punching tools because of high wear resistance [3]. Since the fatigue strength is strongly depended on the surface conditions [4][5][6][7], it is expected that an appropriate surface modification by dynamic ion mixing process can improve the fatigue resistance of materials.…”

Four point bending fatigue tests were carried out using martensitic stainless steel with TiN film deposited at five different deposition rates by dynamic ion mixing process in order to investigate the influence of deposition rate on the fatigue strength. As a result, the fatigue limit clearly increased by the deposition at appropriate conditions. However, the deposition by other conditions resulted in the degradation of fatigue strength. This is caused by the decrease of threshold stress intensity factor after TiN deposition and the difference of defect distribution in the film. In addition, the crack propagation rate was increased in low stress intensity factor range by the deposition of TiN film.

“…To date, functionally gradient materials have been investigated extensively mainly in the field of inorganic materials. [1][2][3][4][5][6][7][8][9][10][11] However, in the field of organic materials, reports are relatively limited. [12][13][14][15][16] In fact, such research started in the field of metal or ceramic materials because the procedure to make gradient components of organic macromolecules is difficult.…”

A silicone sheet was dipped into n-butyl methacrylate monomer including benzoyl peroxide and was swollen for 0.5 h at 23°C. Then, the sheet was put into a glass tube equipped with a three-way stopcock and was deoxygenated by freezing under dry nitrogen. Polymerization was carried out by heating at 80°C for 2 h under dry nitrogen. The resultant sheet was a component gradient silicone sheet with poly-n-butylmethacrylate. The content of poly-n-butylmethacrylate increased gradually from either surface to the middle of the sheet. This phenomenon was assumed to occur because of the volatilization of n-butyl methacrylate monomer during the polymerization. The properties of the sheet include increased tear strength and decreased gas permeability.
