  • Methods for machining hard materials using alcohols
    Patent number: 6206764
    Abstract: The present invention provides a method for machining hard materials using the machining fluids containing long chain alcohol in which the machining fluid is applied to a machining tool and then lubricates the machining of the workpiece by the machining tool and protects the machining tool during machining. The method is particularly useful when used with machining tools having a Mohs hardness of at least 9 and is most particularly useful when used with diamond machining tools.

  • Friction and wear resistant coating for titanium and its alloys
    Patent number: 5633086
    Abstract: For titanium and titanium alloys in tribological applications under bound lubrication conditions, there are employed epoxy coatings adhered to the surface of the titanium or titanium alloy by a titanium oxide primer layer. The anti-wear properties of the epoxy coating can be improved by incorporation of an anti-wear filler such as diamond powder. These coatings improve the friction coefficient and anti-wear properties of the titanium and titanium alloys.
