摘要： PURPOSE:To satisfy characteristics required for a body portion and the acute angle portion of the peripheral edge of a nozzle hole portion at the same time by forming a re-melted treatment layer which is treated using high-density energy on the acute angle portion at least of the peripheral edge portion of the nozzle hole portion. CONSTITUTION:On the acute angle portion 3 at least of the peripheral edge portion of a nozzle hole portion 2 in a chamber body 7 made of heat resistant steel, a re-melt treatment layer 8 is formed which is treated using high-density energy with uniformly fine organization and less amount of carbon than the heat resistant steel of base material. As a result, the chamber body 7 is certainly prevented from dropping out of a cylinder head due to transformation and at the same time can be formed as a chamber of satisfactory durability with the nozzle hole portion 2 restrained from being involved in crack.

摘要： PURPOSE:To manufacture aux. combustion chamber simply, easily, and uncostly by forming a blocking part which encloses at least part of one end or both of a hole, at the time of precision casting in such a way as consolidated with a coarse work for chamber. CONSTITUTION:A coarse work 1 for chamber made of austenite type heat- resistant steel having eaves-shaped blocking parts 4 at the ends of a hole 3A is prepared through precision casting. Therein casting material 5 within the hole 3A remains approx. perfectly even after sand shakeoff process. Then the portions 6A, 6B as acute angle part of the jet are subjected to re-melting process by means of TIG arc. The remaining blocking parts 4 are removed in the finish process. Thus existence of the casting material 5 within the hole 3A allows formation of a layer turned into alloy while the shape of the hole 3A is kept as it was even under the condition that high-density energy 7 is impressed at the time of re-melting process. This enables manufacturing coarse works 1 for chamber simply. easily, and uncostly.

摘要： PURPOSE:To obtain a wear resistant member having superior wear resistance of the prescribed parts by alloying the surfaces of the prescribed parts of a Ti alloy member with Al to form wear resistant layers contg. a Ti-Al intermetallic compd. and having a specified concn. of Al. CONSTITUTION:The base material 1 of a valve body is made of a Ti alloy such as Ti-6Al-4V and the surfaces of the parts of the base material 1 requiring wear resistance, e.g., the valve face part 2 and the shaft end part 3 are alloyed with Al. This alloying can be carried out by uniformly spreading pure Al powder on the prescribed parts and irradiating the surfaces of the resulting Al powder layers with laser light to simultaneously melt the Al powder layers and the surface of the base material under the layers. Wear resistant layers contg. a Ti-Al intermetallic compd. are formed and a Ti alloy base material 1 having superior wear resistance is obtd. The concn. of al in the wear resistant layers is regulated to 15-60wt.%.
