Embodiment 1
[0020] A cast iron platform with an anti-rust, wear-resistant and anti-scratch metal protective layer, the protective layer is a hard alloy layer, the hard alloy layer is arranged on the surface of the cast iron platform, and the hard alloy layer includes the following components in weight percentage : Chromium 75.4-80%, nickel 5.0%, iron 6.0%, aluminum 4.0%, copper 2.6%, molybdenum 2.6% and tungsten 1.8%, the thickness of the hard alloy layer is 35μm.
[0021] The production process of the above-mentioned cemented carbide layer is as follows: the cemented carbide layer is evenly sprayed on the surface of the cast iron platform by hot-dip method, and the hot-dip plating uses acetylene and oxygen as the heat source. The specific process flow is as follows:
[0022] (1) Shot peening roughening the surface of the cast iron platform;
[0023] (2) Feed the hard alloy including the following weight percentage components into the flame end of the spray gun through the wire feeding me...
