摘要： PURPOSE:To easily obtain Al and Al alloy parts each having a surface layer having superior wear resistance, smoothness and corrosion resistance by forming a surface layer contg. Cr2O3 produced by the conversion of a Cr compound by heating as the principal component on the surface of a base material contg. Al as the principal component. CONSTITUTION:A soln. contg. CrO3 as the principal component is applied to the surface of a base material made of Al or an Al alloy and the base material is baked by heating to about 450-550 deg.C to carry out oxidation treatment. Thus, a surface layer contg. Cr2O3 produced by the conversion of the CrO3 by heating as the principal component and having a part where Cr2O3 reacted with the base material is present on the boundary between the surface layer and the base material is easily and firmly formed on the surface of the base material without deteriorating the base material. The surface layer is dense, has high hardness and satisfactory adhesion to the base material and does not cause stripping.

摘要： PURPOSE:To permit efficient baking treatment by treating a painted steel sheet by a combination of heating with an induction heater intended only for the evaporation of a solvent and gas heating intended for the inherent baking, i.e., melting and softening of the paint. CONSTITUTION:The steel sheet S is painted on the front side by a painting roll 1 in the position where the steel sheet is wound on a hold back roll 5. The steel sheet is then painted on the rear side by a painting roll 2 between support rolls 6 and 7. The steel sheet is immediately introduced into the induction heater 3 where the greater part of the solvent is evaporated. The steel sheet is introduced into a heating furnace 4 where the steel sheet is subjected to the inherent baking including the melting and softening of the paint. The gas contg. the evaporated solvent in the induction heater 3 is conducted by a suction blower 8 to a combustion furnace 9 where the gas is thoroughly burned by a burner 10. Part of the exhaust gas generated by the combustion is supplied as a dilute gas through a piping 12 to the induction heater 3.

摘要： PURPOSE:To improve corrosion resistance and heat resistance by subjecting the surface of a ferrous sintered metal to a treatment for forming a specifically composed film, or sealing treatment by an iron oxide film or impregnating and sealing treatment by a resin in combination. CONSTITUTION:The sintered bodies of various mechanical parts are produced by compacting, molding and sintering iron powder to desired shapes. The sintered parts are porous and have consequently an easy tendency to oxidation and corrosion and therefore three kinds of the following surface treatments are executed independently or in combination. As the method A, the sintered parts are dipped into a soln. mixture composed of a hexad Cr supplying material such as CnO3, metallic powder of Al, Zn, etc., as the reducing agent thereof and surface active agent and further said parts are heated to 250-400 deg.C to form the film of Zn or Al enclosed with the tervalent Cr polymer on the surface of the sintered parts. As the method B, the parts are heated to a high temp. in an atmosphere contg. steam and hydrogen to form a dense Fe3O4 film on the surface and to seal the surface. As the method C, the holes are impregnated and sealed by water glass or resin. These methods A-C are combined to improve the corrosion and heat resistance of the sintered parts.

摘要： PURPOSE:To form the titled insulated film without the anxiety of brittleness due to the rise in temp. of an amorphous alloy and crystallization by using microwave for drying and baking in case of coating, drying and baking the coating soln. useful in forming the insulated film on the amorphous alloy thin band. CONSTITUTION:After coating a coating soln. on the surface of amorphous alloy thin band (ribbon) 1 with the Wringer roll coater 2 or the like, the thin band 1 is introduced into a baking furnace 3. In this case, the thin band 1 is supported by a roll 4 in the outlet side but it is made so that the roll 4 is not brought into contact with the thin band 1 in the nondrying state. When the baking of the insulated film has been finished, the thin band 1 is wound around a drum 6 while controlling the winding tension by a dancer roll 5. Therein, a microwave is used as a heat source by which the insulated film is dried and baked while the thin band 1 is passed through the furnace 3. Since the coated film of coating soln. on the surface of the ribbon 1 is selectively heated by the microwave, the ribbon 1 itself is hardly heated and the aim is attained.
