Abstract

The invention discloses a corrosion-resistant hard alloy. Rhenium is added into a bonding phase, the bonding phase in the hard alloy is strengthened, and the purposes of improving hardness and corrosion resistance of the hard alloy are achieved. The hard alloy provided can be applied to the preparation of an artificial board saw, the hardness of the prepared artificial board saw is high, the cutting efficiency of the artificial board saw is favorably improved, meanwhile, the chemical corrosion of an adhesive in an artificial board can be resisted, and the service life of the artificial board saw is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of hard alloys, in particular to a corrosion-resistant hard alloy and its application in the preparation of artificial panel saws. Background technique [0002] Wood-based panels are boards or molded products that are made of wood or other non-wood plants, separated into various unit materials by certain mechanical processing, and glued with or without adhesives and other additives. In the production of wood-based panels, in order to improve the performance of the wood-based panels, the veneer on the surface of the wood-based panels needs to be very hard, and the interior wood-based panels need to be added with adhesives during the manufacturing process, which has a certain degree of corrosion. [0003] When further processing wood-based panels, it is usually necessary to use wood-based panel saws to cut the wood-based panels. Because the wood-based panel veneer is hard and there is corrosive glue inside, t...
