Investigation on the effects of shielding gas on porosity in fiber laser welding of T-joint steels
TL;DR: In this article, the porosity number and distribution of keyhole-induced porosity in T-joint steel structures were investigated. And the results showed that appropriate shielding gas flow rate, blowing angle, and distance to molten pool could help to achieve less porosity for this Tjoint, while a high-speed photography was applied to observe the plasma over the keyhole and fluid flow of molten pool to better understand the formation process of porosity.

Preparation, characterization and wear behavior of carbon coated magnesium alloy with electroless plating nickel interlayer
TL;DR: In this paper, the Ni+C composite coating has a dense microstructure, improved adhesion strength and hardness due to the effective support of Ni interlayer. And the wear test result shows that the Ni-+C composites can greatly prolong the wear life of the magnesium alloy.
