Abstract
The utility model relates to a surface ceramic valve plate, which belongs to the technical field of valve parts manufacture. The surface ceramic valve plate comprises a circular substrate (1) and a corrosion resistant and scuff-resistant coating (2) on the surface of the substrate, wherein the substrate (1) is made of aluminium alloy material or titanium alloy material; the corrosion resistant and scuff-resistant coating is made of ceramic matter with an alpha-Al2O3 and gamma-Al2O3 crystal form; and a ceramic coating is formed by a microarc oxidation device. The surface ceramic valve plate has higher corrosion resistance, higher abrasion performance and higher hardness, and thereby, the surface ceramic valve plate has good usability of longer service life and also has a certain environmental protection property and economical efficiency.
Description
Technical field
The utility model relates to a kind of valve block of surface ceramic deposition, belongs to valve components manufacturing technology field.
Background technique
Valve block is a vitals of valve, is a kind of valve opening and closing element with through hole, by moving of valve block, realizes the control of valve convection cell.
Valve block commonly used generally is to be made by metallic material, plastics or stupalith.The problem that exists is: the wear resistance of metallic material valve block and corrosion-resistant, and plastic valve plate is yielding and aging, and the fragility of ceramic valve plate is big.
Summary of the invention
The purpose of this utility model is to provide a kind of novel surface ceramic deposition valve block, overcome the defective of valve block wear resistance and corrosion-resistant difference in the past, develop a kind ofly have good anticorrosive and wear resistance, size shape is stable, not fragile and the novel valve block of long service life.
A kind of surface ceramic deposition valve block of the utility model is made up of the corrosion-proof wear coating of circular substrate and base surface; It is characterized in that substrate is to be made by aluminum alloy or titanium alloy material; Corrosion-proof wear coating is for having α-Al
2O
3And γ-Al

3The coating that the ceramic masses of crystal formation constitutes is by carrying out on the ceramic treatment special device commonly used.Described surface ceramic deposition processing equipment is micro-arc oxidation device or spark anodic oxidation device or little plasma oxidation device.
Be provided with 2-4 circular hole circumferentially equidistant above the described circular substrate, depend on the needs.
The characteristics of a kind of surface ceramic deposition valve block of the utility model are as described below:
The performance outstanding behaviours of surface ceramic deposition layer exists: 1) because ceramic layer is a growth in situ becomes, so with the high base strength height.2) because ceramic layer has the crystalline oxide ceramic structure, so ceramic layer has characteristics such as hardness height, wear-resistant, corrosion-resistant, high pressure resistant insulation and high temperature resistance impact.3) change the composition of Electrolytic solution, can obtain the ceramic layer of decorative colour, and color and luster is stable, not fugitive color.
Valve block is as the vitals of valve, the usability of valve block require be: have high corrosion resistance, high wear resistance and soundness, long service life.Experimental results show that: the utility model surface ceramic deposition valve block, more can satisfy the usage requirement of valve block.
The advantage of a kind of surface ceramic deposition valve block of the utility model is as follows:
(1), Economy is obvious
Aluminum alloy material market is easy to get, and the geomery moulding of valve block is simple, easy to process.Surface ceramic deposition equipment and technology are simple, and it is stable convenient to handle, and take up an area of for a short time, realize the automatic streamline operation easily.
(2), environmental protection
Because the surface of valve block is pottery, and is corrosion-resistant, do not contain hazardous substance yet, so convection cell does not produce pollution, health safe in utilization.The surface ceramic deposition processing procedure also is the course of working of environmental protection, cleaning simultaneously, is different to electroplate and other surface treatments.
(3), usability
Because wear-resisting, the corrosion-resistant and high hardness of ceramic layer has the longer mission life-span thereby give the surface ceramic deposition valve block.
