    The operation of equipment will inevitably have friction, and friction will inevitably be accompanied by wear. Therefore, it is very common for metal friction and wear to appear on equipment, and wear-resistant coatings can provide the surface of mechanical equipment parts with wear resistance, corrosion resistance, High temperature resistance, insulation, high pressure resistance, and oxidation resistance. To improve the service life of metal parts, today we will talk about the performance, function, category and advantages of wear-resistant coatings.

 
 

  Performance characteristics of wear-resistant coating:
  1. Good appearance and color, and can process products of various shapes;
  2. has excellent corrosion resistance and chemical stability;
  3. Excellent metal surface adhesion and rust resistance, which can prevent intermetallic wear, abrasion and sintering;
  4. excellent water erosion resistance and corrosion resistance, low friction coefficient, wide temperature range;
   5. It has the characteristics of anti-friction, prevention of stickiness, high temperature resistance (400℃), etc., suitable for use in high temperature and high pressure environments.
  The role of wear-resistant coating:
  1. it can prevent the firmware from jamming and biting
  Metal equipment coated with wear-resistant coating on the surface is not prone to rust, seizure, or seizure after use.
  2.anti-rust and anti-corrosion
  The wear-resistant coating will form a dense and firm lubricating film on the surface of the workpiece, which cuts off the contact between the metal substrate and the air, making it difficult to rust.
  3. wear-resistant
   Based on the excellent wear resistance and self-lubricity of the wear-resistant coating, metal parts can be loosened and locked repeatedly without damage to the surface of the part.
  4. Lubrication problems are not limited in high temperature and low temperature environments
  Metal equipment parts with wear-resistant coating will not be embrittled due to too low or too high temperature, and still have lubricating properties.

  Use of wear-resistant coating
  Under various special working conditions (such as high temperature, low temperature, high altitude and heavy load, etc.), the performance of general grease cannot be adapted, and the metal surface wear-resistant coating can be used for lubrication.
  Some structural parts and friction pairs cannot be continuously supplied with lubricating grease, installation work is not easy to access or loading and unloading is difficult, and regular maintenance is not possible, such as bridge support bearings, metal surface wear-resistant coatings can be used for anti-wear lubrication.
  The oil film of general lubricating grease can only bear a relatively small load. Once the load exceeds the limit it can bear, the oil film will break and the friction surface will seize. The wear-resistant coating on the metal surface can withstand an average load of 108pa or more.
Transmission parts in electronics, textiles, food, medicine, papermaking, printing and other machinery, transmission parts of cameras, video recorders, copiers, and many household appliances can be coated with EUBO metal surface wear-resistant coating treatment to improve the resistance of product parts Grinding ability.
   Classification of wear-resistant coatings
  1. The wear-resistant coating formed by plasma spraying, arc spraying, flame spraying on the metal surface spraying ceramics, alloys, oxides, fluoroplastics, etc. is generally called thermal spraying wear-resistant coatings.
  2. Wear-resistant coating glue prepared with various resins, elastomers, etc., and the wear-resistant coating obtained by natural or heating curing after coating on the metal surface is called a chemically bonded wear-resistant coating.
   wear-resistant coating can be divided into the following types:
  (1) Adhesive and abrasion resistant coating. Adhesive wear resistant coatings can be divided into soft support surface coatings and hard support surface coatings.
   (2) Wear-resistant grain wear coating
   (3) Fatigue and wear resistant coating
   (4) Erosion resistant coating

 

 

 Advantages of wear-resistant coating
 1. It is composed of polymer materials, wear-resistant orthopedics, ultrafine powder and inorganic polymer dispersion. After the coating is cured, the particles are tightly packed, have good adhesion, are not easy to fall off, and have good thermal degeneration.
  2. The higher abrasion resistance experiment shows that the wear resistance of the wear-resistant and waterproof coating is 10 times that of 16Mn steel, 9 times that of 65Mn steel, and 50 times that of refractory castables. With the increase of temperature, the resistance of wear-resistant and waterproof coating Little change in grinding performance.
 3. The wear-resistant coating has stable performance, and uses special materials that are acid and alkali resistant, and it is not easy to react with the medium. Can be very resistant to environmental corrosion.
 4. Specially made of excellent resin, with stable molecular structure and not easy to decompose due to aging.
