Presented at ICALEO 2011
Laser direct metal deposition (LDMD) is a rapid manufacturing technique, with high potential for development, from new part construction to worn or defective part repair, with various metallic alloys. Thanks to their long experience in the field of laser cladding, IREPA LASER has developed specific tools adapted to the rapid manufacturing of metallic parts based on their patented coaxial powder cladding nozzle.
The process is well developed, but depends on numerou...$28.00

High corrosion rate in physiological environment of body is the major drawback of magnesium alloys for their application as biodegradable orthopedic implants. Bulk metallic glasses (BMGs) are relative newcomers in the field of biomaterials but they exhibit an excellent biocompatibility such as Zr60Ti6Cu19Fe5Al10 BMGs. The aim of this presentation is to deposit Zr60Ti6Cu19Fe5Al10 amorphous layer o...$28.00

In the present work, laser direct deposition is used to build multi-layer structures of nickel-based alloy IN690 reinforced with titanium carbide particles at 5-25 percent by volume. This study shows the effects of various operation parameters including the initial weight ratio of matrix and reinforcement powders. The relationship between final TiC volume fraction in the depositions and TiC volume fraction in the initial powder mixture shows good retention of carbide part...$28.00

Presented at ICALEO 2011
In this paper, the effect of powder composition on TiC morphology and clad hardness using in-situ laser cladding process has been studied. Two atomic ratios, 45% and 55%, were selected for C:Ti, the first one of which has the potential to form TiC without formation of the preliminary Ti (α) phase. Results show that chemical composition affects the TiC morphology, TiC distribution ...$28.00

Recently high-power, high-quality disk lasers are developed to produce deep penetration welds. This study was carried out to produce deep-penetration weld beads and to interpret the effect of combined beams on welding results and phenomena by using high power disk lasers of 10 kW and 16 kW. It was consequently confirmed that twin...$28.00
