Ion beam technique makes surfaces smoother, harder

17 Jun 2002

A low-cost ion beam technique developed at Sandia National Laboratories is expected to double or triple the life expectancy of products ranging from tools and dies to jet engine blades.

Created on a small scale in Russian laboratories and made practical in the United States, the beam is composed of light-weight ions -- atoms with positive electrical charges -- that bombard surfaces, making them smoother or harder. The beam also improves the bonding and hardening of plastics and may significantly lengthen the life spans of certain medical implants. Two former Sandia researchers have obtained exclusive license to the relevant patents and are commercializing the technology through their company, Quantum Manufacturing Technologies, Inc.
