Preparation method of ceramic electrician blade

Abstract

The invention discloses a preparation method of a ceramic electrician blade, belonging to the field of preparation method of special blades. The processing method comprises the following steps: (1) sintering of a ceramic blank; (2) sharpening both sides of the knife; (3) cutting a breaking groove; (4) processing a big knife edge; (5) processing a small knife edge; (6) accurate grinding of the small knife edge; (7) checking the knife blade; (8) packaging, etc. In the invention, a hot isostatic pressing method is adopted for sintering the raw material, the best sintering technology is selected according to the material composition, and some substances in an adhesive can be fully carbonized at 1,400 DEG C; and the carbonized components can promote the whisker toughening of aluminum oxide, and the toughness of the blank is enhanced. In the invention, during blade processing, the processing depth of the breaking groove is strictly controlled according to the length, width and thickness of the blade, and the defective percentage of the product is reduced.

Description

technical field

[0001] The invention belongs to the technical field of preparation methods of special blades, and more specifically relates to a preparation method of ceramic electrical blades. Background technique

[0002] The ceramic blade is a new type of blade made of high-tech nanotechnology. Its sharpness is more than ten times that of steel knives. Most of the ceramic knives on the market are processed with a nano-material "zirconia". Use zirconia + alumina powder to press 300 tons of heavy pressure with a mold at a high temperature of 2000 degrees to make a knife blank, and then polish it with diamonds and match it with a handle to make a finished ceramic knife. Although ceramic knives have incomparable advantages over traditional metal knives, their shortcomings are also difficult problems that cannot be overcome in the field at present. Because ceramic knives are all sintered from zirconia, their hardness is determined by the nature of their raw materials. 9, but ...
