A manufacturing method and equipment for a novel smokeless pan based on ion beam technology

Abstract

The invention discloses a method and equipment for manufacturing a novel smokeless pan based on an ion beam technology. The manufacturing method of the smokeless pan comprises the following steps of: depositing a super-hard diamond-like film layer, which is good in heat conductivity and is nontoxic and environmentally friendly, at the bottom of a pan by taking an aluminum alloy, stainless steel or an iron pan as a matrix. A specific deposition method comprises the following steps of: injecting metal Ti ions into the surface of a pan base by adopting metal vapor vacuum arc ion source (MEVVA) so as to form a metal 'pinning layer', and then depositing a first layer namely a metal Ti stress release layer on the surface of the base by adopting a 90-degree magnetic filtered metallic cathodic vacuum arc (FCVA) technology; and depositing a second layer namely a super-hard diamond-like film layer on the first layer namely the stress release layer by adopting a 180-degree FCVA method, wherein the total thickness of the two-layer composite film is 0.1-10 microns, the heat conductivity of the film layer is 500-1000W / m.K which is 20 times or above of that of an iron pan, and meanwhile, the hardness of the film layer is 60Gpa which is 15 times or above of that of iron, stainless steel or aluminum alloy. By implementing the method disclosed by the invention, a novel smokeless pan which is applicable to various types of turners and is long in service life can be manufactured.

Description

technical field [0001] The invention relates to the technical field of surface modification of ray beam materials, in particular to a method and equipment for manufacturing a smokeless pot by depositing a super-high thermal conductivity and superhard diamond-like film on the bottom of a common pot. Background technique [0002] With the improvement of people's living standards, the requirements for pots are also getting higher and higher. Reducing or avoiding cooking fumes is the basic requirement for people on pots. Smokeless pot products are used in this environment. The principle of the existing smokeless pot is to adopt special molding technology, integrate the principles of conduction, convection, and radiation, and improve the thermal conductivity of the pot, so that the heat transfer of the pot is fast, the heat is uniform, and there is no local high temperature. When cooking and heating, the temperature difference in the pot is not small. It will be higher than 50°C,...

AI Technical Summary

Problems solved by technology

Existing methods for manufacturing smokeless pans include the following: a) Spraying DuPont’s Teflon coating on the surface of the bottom of the pan. The base material is hard oxidized aluminum alloy, which has the advantage of uniform heat conduction and non-stick pan; The disadvantage is that you can't use shovels and steel balls, you can't rinse with cold water directly after cooking, and you can't use strong fire. Another fatal disadvantage is that Teflon is made of polytetrafluoroethylene or polyfluoroethylene propylene as the main material, and polytetrafluoroethylene is a carcinogen

b) Two layers of pots are used to make a sandwich pot with a hollow center. Water or other liquids are usually poured into the middle to achieve uniform heat conduction. The advantage is that it can be used for any shovel without any maintenance. The disadvantage is that the base is aluminum alloy. A long time will form an aluminum oxide film on the surface, and salty dishes or soups will be stored in it, which will produce chemical changes and cause adverse effects on the body
