摘要： The piston ring of the present invention comprises a thermal spray coating comprising chromium carbide particles having an average particle size of 5 mu m or less, and a matrix metal composed of a Ni-Cr alloy or a Ni-Cr alloy and Ni at least on an outer peripheral surface, said thermal spray coating having an average pore diameter of 10 mu m or less and a porosity of 8% or less by volume. A piston ring having excellent wear resistance, scuffing resistance and peeling resistance with little attackability on a mating member is obtained by forming a homogeneous thermal spray coating having a fine microstructure.

摘要： PURPOSE:To provide a piston ring material which is composed of fixed components, and has net-shaped nonsolved carbide in tempered martensite or bainite base to obtain fixed hardness, and thereby becomes excellent in rigidity, antiscarfing ability, and wear resistance, and is suitable for a marine Diesel engine etc.. CONSTITUTION:A cast steel piston ring material is composed of 0.6 to 1.0% of C, 2.0% or less of Si, 2.0% or less of Mn, 0.05% or less of P, 0.10% or less of S, 10 to 14% of Cr, 0.2 to 1.5% of Mo, 0.03 to 0.15% of V which are all in weight ratio, and remainder being practically Fe and impurities. A tempered martensite or bainite base has 5 to 20% net-shaped nonsolved carbide, whose hardness is set up to be HRC 32 to 45. Thus, in addition to antibreaking ability of steel, the net-shaped carbide is deposited by casting to produce the cast steel piston ring material being excellent in antiscarfing ability and wear resistance.

摘要： PURPOSE:To improve the dimensional accuracy of a cam body by longitudinally dividing said cam body in two in the axial direction and previously forming an oil groove. CONSTITUTION:The cam peaces 1a, 1b of green compact are prepared by longitudinally dividing a cam body 1 in two in the axial direction and forming oil grooves 4a, 4b on their opposite faces A, B respectively at the time of molding. When the cam pieces 1a, 1b are sintered in liquid phase, projections 5a, 5b and grooves 6a, 6b for positioning which are fitted in each other are provided on the mutually opposite faces A, B respectively, to prevent the existence of dislocation or a step on a cam form. Then, a steel inner ring 2 in which a serration is machined on the meshing part 7 of its inner peripheral surface so as to be combined with a shaft, is assembled. Thereby, a cam body 1 having an oil port 4 in a hard sintered alloy part, can be manufactured.

摘要： PURPOSE:To locate the phase of a cam easily and with good accuracy and to obtain a strong combination by reducing the expansion of a pipe by fitting the unevenness in triangular tooth serration shape of the cam to the triangular tooth serration shaped unevenness of a steel made pipe and by expanding the steel pipe. CONSTITUTION:The unevenness 4 of triangular tooth serration shape is formed in parallel to the longitudinal direction of the whole periphery of the outer peripheral face of a steel made pipe 1 and the triangular tooth serration shaped unevenness 5 which is fitted to the unevenness 4 of the pipe 1 is formed on the inner peripheral face of the cam 2 consisting of wear resistant material. The shape of the unevenness 5 of the cam 2 is formed lower in its triangular tooth and larger in its angle than the shape of the unevenness 4 of the pipe 1..The cam 2 is strongly combined to the pipe 1 by expanding the pipe 1 by fitting the unevenness 5 of the cam 2 to the unevenness 4 of the pipe 1 corresponding to the phase position of the cam 2.

摘要： PURPOSE:To obtain a piston ring with excellent abrasion resistance and scuff resistance by using a steel material with the specific composition for a base material and forming a hardened layer via nitriding on the outer periphery sliding face. CONSTITUTION:A piston ring is made of 0.4-1.0 wt.% C, 3.0-10.0 wt.% Cr, 3.0-10.0 wt.% Mo, 1.0-2.5 wt.% V, 1.0-3.0 wt.% W, 2.0-10.0 wt.% Co and the remainder of Fe and inevitable impurities. Nitriding is applied at least on the outer periphery sliding face of this base material to form a hard film layer. Among the added elements, C is solid-solved in a substrate to increase the hardness and bound with Cr, Mo, V and W to form a hard carbide. Co forms no carbide and does not contribute in improving abrasion resistance, but it is solid-solved in the substrate and improves temper hardness and red heat hardness. As clearly shown in the test results of a test piece A thus manufactured, the piston ring with excellent abrasion resistance and scuff resistance and rarely abrading a mating material is obtained in this method.
