Wear-resistant Ceramic Parts

Wear-resistant ceramic parts: Alumina wear-resistant ceramic sheets, the content of AI2O3 reaches 97%, after sintering above 1650 ℃, the mechanical strength, wear resistance and other aspects are superior to various similar wear-resistant ceramic products on the market. The ceramic module with an area of 10×10 mm and a thickness of 1-2 mm is an ideal product to replace the widely used products with a thickness of 3 mm and above. Because the thickness is reduced by half or more, it is relatively light in weight, convenient in construction, and more firmly bonded. It is not easy to fall off under high-speed operation and vibration, and the cost of use is reduced. It is adopted by various users who pursue high performance and low cost. At the same time, it also produces plates, sheets, columns, nozzles and special-shaped porcelain parts with complex shapes according to customer needs.

Product Feature

Wear-resistant ceramic patch: The wear-resistant ceramic patch and lining brick are made of α-AL2O3 as the main raw material, supplemented by rare metal oxides and other fluxes. Its super hardness, super wear resistance, high temperature resistance and corrosion resistance and other excellent properties make it incomparable with other wear-resistant materials such as cast stone and cast steel. It is a high-quality special wear-resistant material for industrial use. According to the experimental comparison of the state department, the wear resistance of wear-resistant ceramics is more than 30 times that of manganese steel, and more than 6 times that of high-chromium cast iron.

Wear-resistant ceramic parts are widely used in coal conveying, pulverizing, and ash discharge systems of thermal power generation, as well as material conveying and batching systems in metallurgy, steel, cement and other industries. Such as coal mill outlet pipe, coarse and fine powder separator inlet pipe, primary air duct elbow, pulverized coal pipe, dust removal pipe, ash falling pipe, etc.

Features

1: Excellent wear resistance, continuous use for more than ten years. The wear resistance of special ceramics is 266 times that of manganese steel. The lining ceramic has high strength, high hardness and light weight.

2: The Rockwell hardness of corundum ceramics is HRA80-85, which is much higher than that of wear-resistant steel and stainless steel. The density is half that of steel, and the weight is only 1/3 of the wear-resistant steel pipe, which is easy to install and replace

3: The installation is firm, with good heat resistance and corrosion resistance. The ceramic sheet is attached to the inner wall of the elbow with a high-temperature inorganic adhesive. Ceramics are inorganic materials, which do not oxidize and corrode, and are resistant to acid and alkali corrosion.

4: The inner wall is smooth and does not block the powder. Product Specifications Standard products are manufactured according to national standards, and non-standard products are manufactured according to drawings provided by customers.

Zirconia wear-resistant ceramic parts must have been used, such as some ceramic rods, ceramic heat insulation plates, wear-resistant ceramic tubes, etc. are relatively common, then let me introduce the components of zirconia wear-resistant ceramics.

Method Step

Because oxide ceramics have good wear resistance, corrosion resistance and good mechanical properties, more and more oxide ceramic materials have been used in many fields to manufacture wear-resistant parts.

In the past, wear-resistant parts were mostly made of traditional alumina wear-resistant ceramic materials, which can meet the needs of their wear resistance in general working environments.

However, in recent years, with the continuous progress and development of new ceramic material technology, the wear resistance and mechanical strength of zirconia wear-resistant ceramic parts made of traditional alumina ceramic materials in some fields cannot meet the working requirements.

Structural ceramic materials with higher strength and better wear resistance must be used. Zirconia Toughened Alumina Ceramics (ZTA for short) material is mainly a kind of complex fine ceramic material formed by introducing quantitative phase change material zirconia in the alumina matrix matrix.

This composite ceramic material not only shows the high toughness and high strength of zirconia wear-resistant ceramics, but also retains the advantages of high hardness of alumina wear-resistant ceramics. Abrasion resistance has also been greatly improved.

Application

1. The field of consumer electronics accessories

The main application area of wear-resistant ceramic parts is the back cover, which is mainly the upgrade and supplement of plastic, glass, and metal materials, followed by patches for fingerprint recognition or wearable device casings.

Mainly benefiting from the increase in the installation rate of fingerprint readers and the replacement of sapphire, it is used for small structural parts such as lock screen and volume keys, which is a continuation of the key business of ceramic parts in the era of functional phones.

2. High temperature alloy filtration field

Ceramic products made by wear-resistant ceramic parts sintering manufacturers are also widely used in the field of superalloy filtration.

Not only zirconia wear-resistant ceramic parts can also exert their excellent and stable use effect in the field of filtration in the field of molten steel casting, and the use of foam ceramic products can effectively and completely remove non-metallic impurities mixed in molten steel.

3. The field of auto parts

Because zirconia wear-resistant ceramic parts are extremely strong, and good toughness is also a significant advantage of this ceramic product. Therefore, with these two advantages, zirconia wear-resistant ceramic parts are widely used in the field of auto parts.

Generally, zirconia wear-resistant ceramic products can be used in related components of the engine, such as connecting rods and piston caps, which will greatly increase the market demand for wear-resistant ceramic parts.
