Laser coating technology makes the drill bit more durable

U.S. coated Services Laser Laser coating techniques can be used to improve the reliability of various products in the harsh marine environment, especially useful for improving oil and gas drilling tools (drill bit) and the wear resistance performance. The application of this new technology extends the life of products used in marine environments by reducing the erosion and erosion of downhole tools.
The new technology comes from a special coating project used at the Stennis Aerospace Center to test rocket engines. The technician applied laser coating to a stainless steel substrate to create a durable and effective coating. Seal.
Laser coating is a special metal surface strengthening process that uses a laser-derived controlled heat to apply a powdered metal material to the surface of the substrate for surface strengthening. 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.
