Problems solved by technology

However, due to the shortcomings of the aluminum alloy itself, such as not ideal wear resistance, insufficient hardness, etc., most of the iron soleplates currently on the market add a layer of coating material on the surface of the aluminum alloy material. Common coating materials include ceramic composite materials, metal alloys, etc. , polyester, etc., the coating not only protects the metal substrate from scratches, but also increases the mechanical properties of the soleplate of the iron
However, due to insufficient bonding between the coating and the metal substrate, long-term use will cause the coating to fall off, affecting the use effect

The aluminium sole plate comprises an aluminium alloy base part and the ceramic layer formed through micro-arc oxidation for the surface of the aluminium alloy base part, wherein the aluminium alloy base part comprises the following components in percentage by weight: 1-3% of Si, 0.2-0.5% of Cu, 0.05-0.1% of Mg, 0.1-0.2% of Zn, 0.5-1% of Sr, 0.1-0.5% of Y, 0.2-0.4% of Fe, 0.1-0.7% of Mn, 0.2-0.5% of Sc and the balance Al and inevitable impurities. According to the aluminium sole plate disclosed by the invention, the binding force of the ceramic layer and the aluminium alloy base part is greatly improved, the service life of the ceramic layer is prolonged, and the aluminium sole plate has the advantages of being abrasion-resistant, anti-wear and anti-sticking.

Description

technical field [0001] The invention relates to the technical field of iron soleplates, in particular to an iron soleplate made of ceramic layer aluminum with strong bonding force. Background technique [0002] Due to its excellent thermal conductivity, the heat transfer effect of aluminum alloy is 16 times that of stainless steel, and it is lighter, so it is often used to make iron soleplates. However, due to the shortcomings of the aluminum alloy itself, such as not ideal wear resistance, insufficient hardness, etc., most of the iron soleplates currently on the market add a layer of coating material on the surface of the aluminum alloy material. Common coating materials include ceramic composite materials, metal alloys, etc. , polyester, etc., the coating not only protects the metal substrate from scratches, but also increases the mechanical properties of the soleplate of the iron. However, due to insufficient bonding force between the coating and the metal substrate, lon...
