Abstract

Cloth is coated at a temperature below about 1000/sup 0/C with amorphous boron-carbon deposits in a process which provides a substantially uniform coating on all the filaments making up each yarn fiber bundle of the cloth. The coated cloths can be used in the as-deposited condition for example as wear surfaces where high hardness values are needed; or multiple layers of coated cloths can be hot-pressed to form billets useful for example in fusion reactor wall armor. Also provided is a method of controlling the atom ratio of B:C of boron-carbon deposits onto any of a variety of substrates, including cloths.

Boron hydride polymer coated substrates

Patent Pearson, R.K.; Bystoff, R.I.; Miller, D.E.

A method is described of coating a substrate with a uniformly smooth layer of boron hydride polymer, comprising: (a) providing an apparatus for generating a boron hydride plasma. The apparatus has a wall means defining a sealable plasma chamber, inlet and outlet means operatively connected to the chamber, and means for generating a plasma discharge within the chamber; (b) disposing a substrate within the chamber; (c) evacuating the chamber through the outlet means; (d) introducing a boron hydride feedstock into the chamber through the inlet means; and (e) generating a plasma discharge within the chamber simultaneously with the introduction ofmore »« less
Boron hydride polymer coated substrates

Patent Pearson, R.K.; Bystroff, R.I.; Miller, D.E.

A method is disclosed for coating a substrate with a uniformly smooth layer of a boron hydride polymer. The method comprises providing a reaction chamber which contains the substrate and the boron hydride plasma. A boron hydride feed stock is introduced into the chamber simultaneously with the generation of a plasma discharge within the chamber. A boron hydride plasma of ions, electrons and free radicals which is generated by the plasma discharge interacts to form a uniformly smooth boron hydride polymer which is deposited on the substrate.
One-directional uniformly coated fibers, method of preparation, and uses therefore

Patent Newkirk, L.R.; Riley, R.E.; Valencia, F.; ...

A problem addressed by this invention was how to obtain very long lengths of refractory metal-coated multifilamentary yarns having a uniform coating on the filaments which make up each yarn, the coating being uniform throughout the length of the yarn such that the coated yarns are suitable for being woven and are suitable for a variety of other uses. The solution is a continuous process which employs a chemical vapor deposition reaction at relatively low temperature and pressure and a separation of the gaseous reaction products from the coated yarn prior to allowing the coated yarn to cool.
