Abstract

PURPOSE:To perform silver soldering and bright quenching by placing super hard alloy materials on base materials, disposing silver solder therein, and passing these into a bright quenching furnace filled therein with a gaseous mixture lighter than air thereby expelling the air stuck on the materials thoroughly in the inlet part of the furnace. CONSTITUTION:Super hard materials 17 are placed in the prescribed positions of base materials 15 consisting of steel materials of ferrous or ferritic structure or steel materials of martensitic structure. Flat plate-like silver braze pieces 18 are interposed in their joined parts, and these are placed on trays 10, and are carried into a bright quenching furnace 1. When the materials 11 consisting of the materials 15 and the materials 17 enter the inlet part 3 of the furnace cylinder, the air stuck thereon is expelled by a gaseous mixture which is filled in the furnace cylinder, consists of helium and argon and is lighter than air at an ordinary temp. Also, the materials are preheated. In a central part 2, they are heated to high temps., then the pieces 18 melt and infilter the contact surfaces 19 between the materials 15 and the materials 17. In an outlet part 4, they are cooled and are bright-quenched.
