Plasma non-stick pan and fabrication method thereof

Abstract

The invention discloses a plasma non-stick pan and a fabrication method thereof. The plasma non-stick pan comprises a pan body and a non-stick coating, and the pan body is coated with the non-stick coating. A plasma layer is arranged between the non-stick coating and the pan body and comprises a MCrALY layer and a mixture layer coated on the outside of the MCrALY layer. The mixture layer is formed by MCrALY particles and metallic oxide particles. The MCrALY layer is good in toughness, high in bonding force, capable of being easily bonded with a substrate, high in bonded firmness and capable of providing a buffer effect well and laying a foundation for subsequent mixture layer coating. The MCrALY particles and the metallic oxide particles are blended in the mixture layer, so that high rigidity and brittleness are provide, and the pan body surface rigidity and anti-abrasion performances are improved greatly; by the buffering effect of the MCrALY layer, the mixture layer and the MCrALY layer are bonded firmly, reliably and enduringly in the condition that the high rigidity and brittleness of the mixture layer is guaranteed.

Description

technical field [0001] The invention belongs to the field of kitchen utensils, in particular to a plasma non-stick pan and a manufacturing method thereof. Background technique [0002] A pot is a common cooking tool in the kitchen. In order to facilitate cleaning and cooking dishes, more and more people use non-stick pans, but there are many defects in the existing non-stick pans. For example, the current die-casting pan body needs to be molded many times before it can be formed, which is time-consuming and labor-intensive, and the work efficiency is low. ; Another example is that Chinese patent CN102871529 discloses a kind of aluminum alloy non-stick pan with a hard surface and its processing technology. Its operation process is forming→finishing→oxidation→spraying→sintering. It is impossible to completely remove the oil stains and burrs carried in the manufacturing process. Although there are some degreasing and cleaning operations in the prior art, they cannot achieve go...

AI Technical Summary

Problems solved by technology

Then some people in the industry tried to increase the hardness by spraying a layer of ceramic coating on the aluminum substrate by plasma technology, because the plasma ceramic coating has extremely high hardness (hardness reaches 1800HV) and high corrosion resistance; but there are two problems in this process. One fatal problem is that the plasma ceramic oxide layer is too brittle, and it is brittle when bonded to the aluminum substrate, and it is easy to crack when hit with a shovel; the second is that the plasma layer and the non-stick coating have poor bonding force, and the plasma layer is very dense. It cannot be effectively combined with the PTFE coating at all, and the service life will be shorter after the coating is sprayed on
