Abstract: PURPOSE:To improve oxidation resistance and wear resistance and to lighten the weight by providing an Al pack cementation layer in which thickness, hardness, and Al concentration are specified, respectively, at least to the surface of the head of an engine valve composed of Ti-Al alloy. CONSTITUTION:An Al pack cementation layer is provided at least to the surface of the shade of an engine valve composed of Ti-Al alloy. The thickness, hardness Hv, and Al concentration of the Al pack cementation layer are regulated to 10-100mum, 300-450, and 42-53wt.%, respectively. The above Al pack cementation is carried out, e.g. by filling a semi-airtight vessel with a base material together with a diffusion agent which is a mixture of Al powder, alumina powder, and NH4Cl powder and then performing heating.

Abstract: 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.

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.%.
