摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a rare-earth magnet of highly coercive force.
SOLUTION: The method of manufacturing a rare-earth magnet has a sticking step for sticking a permeating material (Nd-Cu alloy) that can produce liquid phase onto a surface of a magnetic alloy containing a rare-earth element (R1) at a temperature lower than its eutectic point and a permeating step for heating after the sticking step to permeate and diffuse the permeating material into the grain boundary of the magnetic crystal grain of alloy. This will lead a rare-earth magnet to be obtained in which the crystal grain is encapsulated at least by a constituent element of the permeating material, thus enhancing the coercive force of the rare-earth magnet.

摘要： PROBLEM TO BE SOLVED: To provide a cylinder block contributing to improving fuel economy and durability by being equipped with a sliding surface fully satisfying in scuffing resistance and coefficient of friction.
SOLUTION: After forming a thermal-sprayed layer 3 by thermal spraying a metallic material on the inside face 2 of a bore of a block base body 1 of a cylinder block made of light alloy, a sliding face 4 is made by honing the surface of the thermal-sprayed layer 3.

By keeping the pit area rate Sp within the range of 5-14%, oil maintaining capacity becomes sufficient and scuffing resistance is improved. By making the surface roughness [Rk+Rpk] 0.9μm or lower, the value of the coefficient of friction is sufficiently low, and fuel economy is improved.
