Embodiment 1

[0026] Embodiment 1: A vacuum pump coating with good wear resistance, comprising the following raw materials in parts by weight: 20 parts of cobalt, 10 parts of boron, 15 parts of titanium, 15 parts of carbon, 10 parts of chromium, 7 parts of potassium, 9 parts of sodium, 12 parts of nickel, 17 parts of copper, 15 parts of silicon, 7 parts of hafnium, 5 parts of zirconium, 4 parts of lanthanum, 30 parts of yttrium oxide, 15 parts of rare earth chloride, 10 parts of tetrahydrofuran, 30 parts of absolute ethanol, 20 parts of dilute hydrochloric acid.

[0027] see figure 1 A method for preparing a vacuum pump coating with good wear resistance, comprising the steps of:

[0028] S1, crushing: add cobalt, boron, titanium, carbon, chromium, potassium, sodium, nickel, copper, silicon, hafnium, zirconium, lanthanum, yttrium oxide, and rare earth chloride into the first mixer according to the above weight parts for crushing and Mixing and grinding, stirring for 4 minutes at a rotating ...

Embodiment 2

[0035] The difference between embodiment 2 and embodiment 1 is that the content of its internal components is different, and its preparation method is also adjusted adaptively according to the content of its components. A vacuum pump coating with good anti-wear performance and its preparation method include the following Raw materials in parts by weight: 21 parts of cobalt, 11 parts of boron, 16 parts of titanium, 16 parts of carbon, 11 parts of chromium, 8 parts of potassium, 10 parts of sodium, 13 parts of nickel, 18 parts of copper, 17 parts of silicon, 8 parts of hafnium, zirconium 7 parts, lanthanum 5 parts, yttrium oxide 35 parts, rare earth chloride 16 parts, tetrahydrofuran 11 parts, absolute ethanol 32 parts, dilute hydrochloric acid 22 parts.

Embodiment 3

[0037]The difference between Example 3 and Example is that the content of its internal components is different, and its preparation method is also adjusted adaptively according to the content of its components. A vacuum pump coating with good anti-wear performance and its preparation method include the following weight Parts of raw materials: 22 parts of cobalt, 12 parts of boron, 17 parts of titanium, 17 parts of carbon, 15 parts of chromium, 10 parts of potassium, 12 parts of sodium, 14 parts of nickel, 20 parts of copper, 18 parts of silicon, 9 parts of hafnium, 8 parts of zirconium 6 parts of lanthanum, 40 parts of yttrium oxide, 20 parts of rare earth chloride, 12 parts of tetrahydrofuran, 34 parts of absolute ethanol, and 25 parts of dilute hydrochloric acid.

Abstract

The invention discloses a vacuum pump coating with good wear resistance and a preparation method thereof, and belongs to the technical field of coating preparation. The vacuum pump coating comprises the following raw materials in parts by weight: 20-25 parts of cobalt, 10-15 parts of boron, 15-20 parts of titanium, 15-25 parts of carbon, 10-20 parts of chromium, 7-13 parts of potassium, 9-15 partsof sodium, 12-17 parts of nickel, 17-27 parts of copper, 15-23 parts of silicon, 7-12 parts of hafnium, 5-10 parts of zirconium, 4-9 parts of lanthanum, 30-50 parts of yttrium oxide, 15-25 parts of rare earth chloride, 10-15 parts of tetrahydrofuran, 30-40 parts of absolute ethyl alcohol and 20-30 parts of diluted hydrochloric acid. The prepared coating has better wear resistance and stronger durability and is more suitable for the interior of the vacuum pump, so that the service life of the vacuum pump is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of coating preparation, in particular to a vacuum pump coating with good wear resistance and a preparation method thereof. Background technique [0002] A vacuum pump refers to a device or device that uses mechanical, physical, chemical or physicochemical methods to evacuate the evacuated container to obtain a vacuum. Generally speaking, a vacuum pump is a device that uses various methods to improve, generate and maintain vacuum in a certain closed space. According to the working principle of vacuum pumps, vacuum pumps can basically be divided into two types, namely gas capture pumps and gas transfer pumps. It is widely used in metallurgy, chemical industry, food, electronic coating and other industries; because the gas condenses into particles and dust, it will cause internal wear of the vacuum pump after long-term operation, reducing the service life of the vacuum pump. [0003] The publication number "C...
