Fabrication of reinforcing nanostructured coatings by electron beam processing

In this work, electron beam welding by electron accelerator of tungsten and chromium carbides and subsequent pulse processing by low-energy electrons has been applied for fabrication of nano- and ultradisperse grain structures penetrated by the system of nanosized pores. It has been demonstrated tha...

More Information
Summary:In this work, electron beam welding by electron accelerator of tungsten and chromium carbides and subsequent pulse processing by low-energy electrons has been applied for fabrication of nano- and ultradisperse grain structures penetrated by the system of nanosized pores. It has been demonstrated that, in the region of secondary pulse exposure, the nanohardness and elasticity modulus achieve high values. The wear resistance of the modified structure depends on the value of the specific load in the vicinity of contact with indentor.
