Embodiment Construction
[0028] like figure 1 Shown is a metal substrate 3 with thermal spraying anti-sticking and wear-resistant coating, the surface of the metal substrate 3 is provided with a nickel-based alloy coating 2, and the surface of the nickel-based alloy coating 2 is dispersed and bonded with silicon polymerization The material resin layer 1, the silicon polymer resin layer 1 is cured and cross-linked by addition type siloxane resin. The layer thickness of the nickel-based alloy coating 2 is 120 μm, and the surface hardness is HRC50˜HRC60.
[0029] The formulation of the nickel-based alloy coating 2 in this embodiment is as follows: C 0.5-1.1%, Si 3.0-5.5%, B 3.0-4.5%, Cr 15-30%, Fe=5.0%, and the balance is Ni.
[0030] The silicone polymer resin is commercially available from Ningbo Chemical Industry Co., Ltd.: A component: addition type siloxane; B component: composite platinum catalyst.
[0031] The above-mentioned method for the metal substrate with thermal spraying anti-sticking and...
