Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.
As shown in fig. 1, according to the embodiment of the utility model provides a corrosion-resistant gasket, including gasket body 1, gasket body 1's surface is provided with transition layer 2, transition layer 2's surface is provided with boronizing layer 3, boronizing layer 3's surface is provided with thin layer 4, gasket body 1's thickness diminishes gradually along its middle part to its marginal direction, thin layer 4's thickness is followed its middle part and is grown gradually to its marginal direction.
In an embodiment of the present invention, the middle of the gasket body 1 is provided with a through hole 5.
In an embodiment of the present invention, the boronizing layer 3 and the thin film layer 4 have a first coating edge coated on the hole wall of the through hole 5 and a second coating edge coated on the circumferential side of the gasket body 1.
In one embodiment of the present invention, the ratio of the thickness of the middle portion of the gasket body 1 to the thickness of the edge of the gasket body 1 is between 1.3 and 1.8.
In a specific embodiment of the present invention, the ratio of the thickness of the edge of the boronized layer 3 to the thickness of the middle of the boronized layer 3 is between 1.3 and 1.8.
For the convenience of understanding the above technical solutions of the present invention, the above technical solutions of the present invention are explained in detail through specific use modes below.
Corrosion-resistant gasket include gasket body 1, transition layer 2, boronizing layer 3 and thin layer 4. The gasket body 1 is made of high-quality alloy structural steel through heat treatment, and is high in strength. The thin film layer 4 is used as a corrosion-resistant layer, is made of aluminum oxide and has an excellent corrosion-resistant effect. The boronizing layer 3 can effectively improve the outer surface hardness of the corrosion-resistant gasket, cannot be damaged due to extrusion, and is favorable for improving the corrosion resistance.
In order to improve the corrosion-resistant effect at the edge of the gasket body 1, the thickness of the gasket body 1 is gradually reduced from the middle part of the gasket body 1 to the edge direction of the gasket body 1, and the thickness of the thin film layer 4 is gradually increased from the middle part of the thin film layer 4 to the edge direction of the thin film layer 4, so that the thickness of the corrosion-resistant layer at the edge of the gasket body 1 is increased, and the good corrosion-resistant effect at the edge is further ensured.
