Title: Hard and low friction nitride coatings and methods for forming the same

Abstract

An improved coating material possessing super-hard and low friction properties and a method for forming the same. The improved coating material includes the use of a noble metal or soft metal homogeneously distributed within a hard nitride material. The addition of small amounts of such metals into nitrides such as molybdenum nitride, titanium nitride, and chromium nitride results in as much as increasing of the hardness of the material as well as decreasing the friction coefficient and increasing the oxidation resistance.

  • In one aspect of the invention, a method for growth of carbon nanotubes includes providing a graphitic composite, decorating the graphitic composite with metal nanostructures to form graphene-contained powders, and heating the graphene-contained powders at a target temperature to form the carbon nanotubes in an argon/hydrogen environment that is devoid of a hydrocarbon source. In one embodiment, the target temperature can be as low as about 150.degree. C. (.+-.5.degree. C.).
  • The stabilizer invention comprises an improved, generally tubular friction rock stabilizer body for insertion into a borehole formed in a structure such as mine roof or side wall, or other subterranean opening for stabilizing the structure. The body has a maximum transverse dimension greater than borehole in which it is to be inserted, and requires therefore considerable force to effect its borehole insertion. The stabilizer has a facility for attaching a pendant thereto. An end of the body has a threaded nut fixed therein which receives a threaded, elongate, suspension bolt as the pendant. Thus, the pendant bolt, having amore » terminal drive head, can engage and pendantly support an ancillary article, such as a roof plate, remotely from the stabilizer body. The stabilizing invention comprises stabilizing an earth structure through a given depth thereof with a shorter length friction stabilizer by substantially ''bottoming'' the stabilizer in a borehole in the earth structure of the given depth, attaching one end of an elongate extension piece to the ''bottomed'' stabilizer, and mounting an earth structure retention plate, on the opposite end of the extension piece, securely against the earth structure. Finally, the stabilizer-forming invention comprises fixing a pendant-receiving fastener to an end of a standard earth or rock friction stabilizer for pendantly attaching a roof plate, or the like, thereto.« less
