Abstract

PURPOSE:To obtain the magnetron anode which excels in the mass production through formation of the copper anode by fitting the copper block to the steel cylinder to adhere the both close and then giving the press process to the copper block in a temperature atmosphere of a fixed range. CONSTITUTION:Copper disc 42 is formed previously (b), and A' and B' of steel cylinder 41 and copper blank 42 are cleansed to be fitted together and adhered in the room temperature. Under these conditions, the preheating is given at the vane formation temperature of 350-650 deg.C, and then a press process is given to blank 42 at the inside of cylinder 41 to perform the vane formation. After this, the diffusive annealing is given to make sure the pressure bonding intensity to form the product (e). In this method, the good pressure bonding is possible with no breakdown and without buring cylinder 41. The material malformation resistance of the steel cylinder is more than double the copper block malformation resistance at the adhesive formation time, and with the steel of the carbon quantity of 0.45%C or more. Thus, the burning process can be omitted, and the magnetron anode suited for the mass production can be obtained.
