TL;DR: In this article, the mechanisms of some laser-drilling processes, the types of laser used, the quality characteristics of a laserdrilled hole, the effects of drilling parameters, and the advantages and limitations of the laser hole-dilling operation are reviewed.

TL;DR: In this paper, the authors attempted friction surfacing with a stainless steel, aluminium and brass consumables on a mild-steel substrate in the open air and in flowing nitrogen and found that brass and aluminium consumables failed to form a heated layer in contact with the mild steel, high thermal conductivity of either metal being the probable cause of failure.

TL;DR: Friction surfacing of tool steel, inconel, aluminum and titanium rods onto mild steel substrates and (ii) stainless steel, mild steel and inconel onto aluminum substrates was investigated in this paper.

TL;DR: In this article, the authors present a literature survey and discussion of the various methods and mechanisms of Nd: YAG laser marking of plastic and ceramic IC packages, and the effects of the material properties (e.g., the absorptivity and the melting point) and the marking parameters on the mark legibility characteristics, such as the mark contrast and the mark width, are reviewed.

TL;DR: In this article, the authors used the Taguchi technique of experimental design in optimizing the process parameters for drilling deep-holes in nickel-based superalloy, Inconel 718.
