Background
The blades are of a wide variety and can be generally divided into standard and non-standard parts, and non-standard blades are generally referred to as profiled blades, such as "fly-away profiled blades". If the shape is divided into a straight edge blade and a special-shaped blade (comprising a triangular blade, a sharp-angle blade, a circular-arc blade, a tooth blade, a corrugated blade and an inscribed circular blade), and the like. If classified according to the purpose, the medical instrument blade, the industrial blade, the food blade and the like can be divided, and the blade has wide application in daily life and industrial production. The blade is seriously worn in the using process, so the prior blade is mostly made of hard alloy, high-speed steel, tool steel, metal ceramic and other materials.
The existing hard alloy blade with long service life is generally coated with only one layer of hard wear-resistant coating, and the hardness and the durability of the blade are poor, so that the loss of a cutter is accelerated, and the service life of the cutter is shortened.
