Modern textile machinery especially chemical machinery, light, energy saving is fast, the direction of development. The high-speed moving parts of many energy consuming general as far as possible the use of lightweight alloy matrix (such as aluminum) surface hardening and functional coating composite manufacturing.

Textile parts requirements have a well-defined surface shape, which is due to the contact with the fibers in these parts must be oriented, winding, spinning and drawing and winding required fiber effect. For the design requirements of the special surface tension, and the fiber does not cause hair pulling and scrapes, and must also have sufficient wear resistance, in order to meet the requirements of long time stable spinning work, especially the large-scale production of textile industry, this requirement is more prominent. The design and function of the system by thermal spraying coatingpreparation can meet.

The textile industry in the use of A12O3 TiO2 coating with a wide range, although this kind of coating has good resistance to corrosion resistance. But due to A12O3 and TiO2 and other oxides with different proportions of ceramic coating materials with new technology, such as polishing treatment, different after plasma spraying brush after grinding, grinding and sanding the processing method, the coating can obtain different hardness with different surface condition, in order to meet the needs of all kinds of textile properties of fiber. Its characteristics are as follows:

excellent wear resistance of high speed fiber, high hardness and low surface energy properties of oxide ceramic coating, determine its essential wear and friction reduction, which is not easily replaced by other materials

Different ceramic coating after the processing method to make the surface with different profiles, so there will be a different friction. The fiber can be applied to moderate "twist", so that the fiber to achieve the necessary strength and toughness.

the use of spray sprayed surface particles (raised by numerous appropriate processing to eliminate the sharp peak), provide an appropriate surface roughness, and the effect of fiber fiber surface to obtain the necessary "Cashmere", achieve good dyeing, have certain moisture absorption.

Cr2O3 than A12O3 with high hardness and chemical corrosion resistance. Carbide coatings mainly provide abrasion resistance, in the textile industry has a special role. Most parts of textile machinery needs to prepare the surface was smooth, delicate, uniform surface ceramic coating. The thermal spraying processmust grasp the following three aspects: one is the surface roughening sandblasting with fine grained corundum than 0.25mm: two is the particle size range of 5-45 m three powder spraying; coating thickness is generally 0.15-0.20mm. these applications has formed a system in our country, the scale and standardization. The application of textile and chemical fiber industry of ceramic coating ceramic coating accounted for most of the market.

The series of models of welding dryer, water roller, roller roller, ventilation; mercerizing machine under the camshaft roller, and various import cloth iron plate, gear, shaft; guide roller, performance decline in the use of the joint locomotive fabric shaft, the surface wear can by thermal spraying with high performance alloy, ceramic and polymer materials processing technology, improve and extend the mechanical components of the performance and service life.
