CVD of boron

  • 1. Laboratoire Suisse de Recherches Horlogeres, Neuchatel

Description

The deposition of boron on fine wires by the gas-phase reduction of its halides was studied with the aim of producing instrument and jewel bearings. The deposits are hard (HV0.05 = 3400 kp/mm2) and display good lubricant-free frictional behavior against titanium carbide. Deposits of 1.5 mm rod diameter were formed. Radial cracks caused by reaction with the substrate, and the different coefficients of thermal expansion, were observed. Prior deposition of boron nitride reduces diffusion of boron into the substrate, but complete elimination of all internal tensions has not been achieved as yet. (U.S.)
