The present invention relates to a method for forming an amorphous layer on one surface of a second substrate through a simple method of performing laser irradiation on a multilayered metal layer provided on a first substrate.

Disclosed is a technology being implemented in an apparatus for coating a substrate with swarf particles. The apparatus facilitates depositing metal coating onto metal surfaces, polymers, and ceramics. In this apparatus, the grinding process is retrofitted to deposit coatings onto substrates that range from soft (e.g., polymers and aluminium) to hard (e.g., glass-ceramic) materials. The apparatus comprises a sample holder, an infeed, and a grinding wheel. The sample holder holds a substrate to be coated with swarf particles. The infeed holding a work piece. The grinding wheel is mounted at a predefined height over the infeed. The apparatus is used to perform metal coating by depositing the swarf materials on surface of the substrate. It may be noted that the swarf materials are generated by grinding the work piece with the grinding wheel.

A boring bit or other component for horizontal directional drilling is provided which includes a hard faced layer that is preferably made by a laser cladding bead. A subsequent or post heat treatment is applied to modify the heat affected zone (HAZ) to eliminate or reduce the hard brittle regions and/or softer regions in the base iron or steel material of the HAZ. Further, the hard faced layer may be applied in combination with carbide insert teeth that are embedded within the steel base of the boring bit body, such as by press fitting.

A method of forming an implant having a porous tissue ingrowth structure and a bearing support structure. The method includes depositing a first layer of a metal powder onto a substrate, scanning a laser beam over the powder so as to sinter the metal powder at predetermined locations, depositing at least one layer of the metal powder onto the first layer and repeating the scanning of the laser beam.

A coating for a diamond table of a cutting element is described. The coating is employed to fill a plurality of voids left by the manufacturing process that compromise the integrity of the cutting element and the associated downhole tooling. The coating may comprise diamond nanoparticles in a metal matrix and may be used with or without a binder layer applied directly to the diamond table, the coating may alternatively be a pure diamond film coating, and may be employed to fill voids left by the manufacturing process.
