    Abstract: A wear-resistant wrought Al alloy having a desirable high fatigue strength, toughness and flexure strength when subjected to a quenching and an age hardening heat treatment. The Al alloy contains 8.0 to 13.0% by weight of Si, 0.1 to 0.5% by weight of Fe, 1.5 to 5.0% by weight of Cu, 0.4 to 1.5% by weight of Mg, 0.05 to 0.5% by weight of Cr, 0.05 to 0.5% by weight of Ni, an element selected from the group consisting of 0.005 to 0.05% by weight of Sr and 0.05 to 0.3% by weight of Sb, and the remainder being Al and unavoidable impurities, wherein there is no more than 0.04% by weight of Mn as an unavoidable impurity. The Al alloy having Si particles being finely dispersed therein, wherein an average diameter of an equivalent circle of Si particles is not more than 5.00 .mu.m and an average roundness of Si particles is not less than 0.50. The amounts of Fe, Cr and Ni contained in the alloy and the amount of Mn as an impurity are such to prevent Si particles and other intermetallic compounds from enlarging. At the same time, with the above amounts of Sr or Sb, it is possible to reduce the size of the Si particles and to control the shape. Thus the occurrence or propagation of cracking, which is caused by Si particles can be delayed. The Al alloy exhibits the characteristics necessary for a scroll compressor.

    Abstract: A cylinder head is formed by positioning a clad preform including a first and second layer in a casting die cavity with the second layer in communication with the die cavity and the first layer facing outwardly to define a combustion surface. Molten material provided to the die cavity is solidified to form a cast portion metallurgically bonded to the second layer. An aperture of the preform forms a port in fluid communication with a passage of the cast portion. A plurality of dome-shaped preforms may define the combustion chambers of a cylinder head formed by the method. The preform may define a cylinder head face. The first layer may be a steel-based layer, and the second layer and cast portion may be aluminum-based, such that the first layer and combustion surface has higher thermal fatigue strength relative to the cast portion.

    Abstract: As pressure in a water tank rapidly rises when water inside a compressor is evaporated by the high temperature of compressed air and this situation makes the operation unstable, an object of the present subject matter is to address this problem. A water injected scroll air compressor is provided with: an air end of the scroll air compressor; a driving unit that generates driving force for the air end; a compressing path from a suction port to a discharge port; a portion to inject water into the compressing path; a discharge piping of air discharged from the air end; a tank provided on a path of the discharge piping for storing water separated from the compressed air; and a cooler that is provided on the path of the discharge piping between the tank and the air end and cools the compressed air discharged from the air end.
