Plasma non-stick pan and manufacturing method thereof

Abstract

The present invention discloses a plasma non-stick pan and manufacturing method thereof. The plasma non-stick pan comprises a pan body and a non-stick layer applied to the pan body; a plasma layer is provided between the non-stick layer and the pan body, and the plasma layer comprises a MCrALY layer sprayed to the surface of the pan body and a mixture layer sprayed outside of the MCrALY layer, and the mixture layer is composed of MCrALY particles and metal oxide particles. The MCrALY layer has good toughness and strong adhesion, and it is easy to bind with the substrate with high fastness after binding, playing a buffering role and laying a foundation for the subsequent spraying of mixture layer.

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 bonding force between the plasma layer and the non-stick coating is too poor, 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
