摘要： PURPOSE:To secure the feeding state of a constant quantity for the feeding of a powder material to the side of flame spray gun by means of a quantitative feeding means provided on a feeding hopper by maintaining the powder material in the feeding hopper at a constant level all the time. CONSTITUTION:A means to feed a powder material to a flame spray gun consists of a powder material feeding hopper 3, a replenishing hopper 2 positioned on the upper section of the feeding hopper and a quantitative feeding means 5 provided in the feeding hopper 3. Said hoppers 2 and 3 are communicated with each other through a valve 16, and a level sensing means 24 to sense the quantity of the powder material in the hopper 3 is installed in the feeding hopper 3. A time computing operating means 25 to make the valve 16 opening for a given period of time corresponding to a means 24 is provided in said valve 16 to maintain the powder material in the hopper 3 always at a constant quantity level. As a result, the feeding of powder material to the side of flame spray gun by means of quantitative feeding means can be secured in a state of a constant quantity at all times.

摘要： PURPOSE: To improve the wear resistance of a base material and to reduce the sticking quantity of catalyst by heating and melting a raw-material powder of specific composition by means of an ultrahigh speed flame, generated by using a high pressure combustion gas, and allowing the resultant molten raw material to collide against the surface of the base material to form a coating. CONSTITUTION: The thermal spraying material powder has a composition consisting of, by weight, 10-50% matrix material and 90-50% Cr3 C2 powder. The matrix material has a composition consisting of 10-30% Cr, 0-10% Mo, 0-2% C, and the balance Ni. This raw material powder is sprayed via the tip of a raw material supply nozzle 2, mixed with a combustion gas in the outside periphery of the tip of the nozzle 2, and burned. The resultant combustion flame is accelerated by an air flow fed via a compressed air passage and is sprayed in a state of a cylindrical flame at ultrahigh speed. The sprayed thermal spraying material powder is heated and melted in the center of the flame, accelerated, and sprayed via a thermal spray gun 1. The resultant liquid drops of the thermal spraying material are allowed to collide against a base material 100, and a sprayed coating 102 is formed on the surface.

摘要： PURPOSE:To provide a heat exchanger made of an Al alloy having excellent joining strength of tube materials and fins and corrosion resistance by vacuum brazing the bare fins consisting of a specific compsn. to the tube materials thermally sprayed with a brazing filler metal having a specific compsn. CONSTITUTION:The brazing filler metal consisting of an Al alloy which has the alloy compsn. consisting of, by weight %, 6 to 13 Si, 0.5 to 3 Mg, 0.1 to 0.5 Bi and the balance mainly Al or is further added with 0.5 to 8 Zn is thermally sprayed on the tubes made of the Al or Al alloy. The bare fins consisting of the Al alloy which has the alloy compsn. consisting of 0.5 to 2 Mn and the balance mainly Al or is further added with 0.5 to 5 Zn are assembled to these tube materials and thereafter, the tube materials and the fins are joined by vacuum brazing. While the conditions for the vacuum brazing are not particularly limited, vacuum heating is executed at about 590 to 610 deg.C. The brazing filler metal melts and fillet is formed between the tubes and the fins and between the tubes and a header, by which joining is completed. As a result, the joining strength and corrosion resistance are improved.

摘要： PURPOSE:To allow the title apparatus to surely correspond to the quantitative supply of a material and the instantaneous supply thereof to a spray gun accompanying the start of plasma spraying, by incorporating a change-over valve for supplying and blocking the material in the vicinity of a powder nozzle. CONSTITUTION:A change-over valve 9 is operated with the start of the plasma spraying of a spray gun 1 and a supply passage 8 is permitted to communicate with a powder jet nozzle 2 by the change-over valve 9 to supply a powder material to the nozzle 2 of the spray gun 1 from a supply means 4 through the supply passage 8. When the spray gun 1 comes to a non-spray state and the change-over valve 9 is changed over, the supply passage 8 is blocked from the communication with the powder jet nozzle 2 to be allowed to communicate with a return passage 10 and, therefore, the powder material in the supply passage 8 is returned to a hopper 5 without being supplied to the nozzle 2. Therefore, the remaining of the material in the supply passage at the time of non-spraying is eliminated and the powder material is supplied quantitatively at each time of spray and can be uniformly supplied at the start time of spraying.
