Surface meltallizing aluminum cast iron kitchen utensil and spraying process thereof

Abstract

The invention discloses a surface meltallizing aluminum cast iron kitchen utensil. The surface meltallizing aluminum cast iron kitchen utensil includes a kitchen utensil body; the kitchen utensil bodyis provided with a kitchen utensil bottom and a kitchen utensil side wall formed by stretching; the kitchen utensil body is cast iron; and the outer surface of the kitchen utensil body is provided with a metal meltallizing coating. According to the invention, a uniform and dense metal meltallizing coating is sprayed on the kitchen utensil through the meltallizing spray technology; therefore, theuse of non-stick coatings is avoided.

Description

technical field [0001] The invention relates to the field of kitchen utensils, in particular to a surface sprayed aluminum cast iron kitchen utensil. Background technique [0002] Cast iron kitchen utensils have many advantages such as uniform heat conduction, long-lasting heat preservation, and the release of iron ions during cooking, which is beneficial to health. At present, the iron liner used in the market is formed by stretching thick iron plates to reduce costs. Most of the coatings for cast iron are enamel, and the rough surface of the enamel glaze layer and cast iron is just conducive to the combination of the two. However, the existing cast iron enamel pots mostly sinter enamel as a whole, and there are still defects at the end of the enamel glaze layer, and the end If the gap is obvious, it will also affect the appearance. In addition, during use, when the kitchen utensils are dropped or hit, the enamel glaze layer is prone to collapse, resulting in damage to the...

AI Technical Summary

Problems solved by technology

Generally speaking, the metal spray coating formed by flame spraying has weak bonding strength and large porosity; arc spraying has high spraying efficiency and low cost, but has large porosity; although high-speed flame spraying has small porosity, the spraying efficiency is low; Explosive spraying and plasma spraying are expensive

At present, it is difficult to obtain a high-density metal spray coating by a single spray method, especially in the case of taking into account the spraying efficiency and cost, and the metal spray coating has a small porosity.
