Abstract: PURPOSE:To enhance the wear resistance of a cylinder liner, and also to enable the hardness thereof to be freely adjustable in compliance with requirement by forming a hardened layer in which a specific fine intermetallic compound has been dispersed, on the surface of a liner hole in an aluminum-alloy monocylinder block. CONSTITUTION:An aluminum-alloy monocylinder block 01 is turned in such a condition that the liner hole 02 thereof has been chucked by the chucking claws 06 of a rotary positioner 05. On the other hand, a moving shaft 10 is connected to a bellows 11 type optical path system 04 that has been connected to a laser generator 03, and this is driven by a motor 09. By both the rotation of the monocylinder block 01 and the movement of the moving shaft 10, the laser beams 12 introduced unto the liner hole 02 via a mirror 07 are converged by a mirror 08 to the liner hole 02. Thereby, the liner hole 02 is subjected to laser treatment so as to be melted, and a treated layer 13 is formed. Thereafter, the treated layer 13 is rapidly cooled and solidified to form a hardened layer in which a fine intermetallic compound consisting of Ni3Al has been dispersed, and the hardened layer is subjected to honing machining.

Abstract: PURPOSE:To obtain an artificial dental root made of hydroxyapatite (HAP) wherein a dental root part is porous and excellent in bio-compatibility and an inner crown part is dense and excellent in mechanical strength by constituting the dental root part of a porous structure and forming the inner crown part from a dense structure. CONSTITUTION:An artificial dental root made of HAP is composed of a structure wherein the dental root part embedded in a living body is porous and the inner crown part protruding from the living body is dense and the void size of the voids present in the dental root is 50mum or more. In preparing HAP due to a sol-gel method, a foaming agent is added to a sol and gelling is performed at such a stage that the concn. of the foaming agent in a sol is inclined and, thereafter, foaming treatment and sintering are performed.

At this time, since the void size is 50mum or more, the regenerative bone is easily propagated to invade in the voids. Since the inner crown part has a dense structure, said crown part is excellent in mechanical strength as compared with the dental root part and easily bonded to an upper structure.
