Heat transfer model for cw laser material processing

J. Mazumder, +1 more
- 01 Feb 1980 - 
TL;DR: In this paper, a three-dimensional heat transfer model for laser material processing with a moving Gaussian heat source is developed using finite difference numerical techniques, which is physically defined as follows: a laser beam, having a defined power distribution, strikes the surface of an opaque substrate of infinite length but finite width and depth moving with a uniform velocity in the positive x direction.

Fabrication of functionally graded TiC/Ti composites by Laser Engineered Net Shaping

Weiping Liu, +1 more
- 01 May 2003 - 
TL;DR: In this paper, a crack-free functionally graded TiC/Ti composite materials were fabricated by laser engineered net shaping (LENS), with compositions changing from pure Ti to approximately 95 vol% TiC.

Direct laser processing of a tantalum coating on titanium for bone replacement structures.

Vamsi Krishna Balla, +3 more
- 01 Jun 2010 - 
TL;DR: This study has successfully deposited a Ta coating on Ti using laser engineered net shaping (LENS) to enhance the osseointegration properties and shows excellent cellular adherence and growth with abundant extracellular matrix formation on the Ta coating surface compared with the Ti surface.

Arc augmented laser processing of materials

William M. Steen
- 01 Nov 1980 - 
TL;DR: In this paper, it has been shown that an electric arc can be added to the interaction between a laser beam and a material surface in such a way that in welding and cutting it produces an effect similar to that from a more powerful laser.

Advances in modeling the effects of selected parameters on the SLS process

John D. Williams, +1 more
- 01 Jun 1998 - 
TL;DR: In this article, the analytical problem describing the energy delivery, heat transfer and sintering process along with other pertinent phenomena is studied, and the effects of selected parameters on the SLS process response are examined.
