Jinan University wear-resistant coating technology passed the appraisal
Laser coating technology from a US company can improve the reliability of a variety of products used in harsh offshore environments, especially for improving the wear resistance and performance of oil and gas drilling tools such as drill bits. The application of this new technology extends the life of products used in marine environments by reducing abrasion and erosion of downhole tools. The new technology comes from a special coating project used at the Stennis Aerospace Center to detect rocket engines. The technician applied laser coating to a stainless steel substrate to create a durable and effective coating. Sealed. Laser coating is a special metal surface strengthening process. The principle is to apply a certain powder metal material to the surface of the substrate to achieve surface strengthening by using the controlled heat from the laser. Laser coating provides a stronger metallurgical bond between the two metals with minimal matrix metal dilution. The heat input required for this process is minimal and the resulting heat affected zone is also small. Only a small area of ​​the substrate material is melted together with the coating material during the coating process to produce a metallurgical bonding effect. Moreover, the thermal energy input of the process can be precisely controlled, so that the resulting dilution is minimal, and this small amount of thermal energy input prevents product distortion and has minimal impact on the properties of the substrate material. Hexagon socket head screws, also referred to as hexagon socket bolts, cup head screws and hexagon socket head screws, are different in terms of their names, but they represent the same meaning. The commonly used hexagon socket head cap screws are also 4.8, 8.8, 10.9 and 12.9. Also known as hexagon socket screws, also known as hexagon socket bolts. Its head is hexagonal and cylindrical.
