An aluminum-boron-carbon abrasive article is comprised of at least three phases selected from the group consisting of: B.sub.4 C; AlB.sub.2 ; AlB.sub.12 ; AlB.sub.12 C.sub.2 ; Al.sub.4 C.sub.3 ; AlB.sub.24,C.sub.4 ; Al.sub.4 B.sub.1-3 C.sub.4 ; AlB.sub.24 C.sub.4 and Al.sub.4 BC. At least a portion of the surface of the abrasive article is comprised of abrasive grains of at least one phase selected from the group consisting of AlB.sub.24 C.sub.4, Al.sub.4 BC and AlB.sub.2, where the abrasive grains have an average grain size that is at least about two times greater than the average grain size of the grains containing boron and carbon within the abrasive article. The aluminum-boron-carbon abrasive article of claim 1 is prepared by heating, under a vacuum or inert atmosphere, a body comprised of at least one boron containing phase and at least one carbon containing phase in the presence of a separate source of aluminum, such as aluminum metal or alloy thereof. The boron and carbon containing phase each are selected from the group consisting of: B.sub.4 C; AlB.sub.2 ; AlB.sub.12 ; AlB.sub.12 C.sub.2 ; Al.sub.4 C.sub.3 ; AlB.sub.24,C.sub.4 ; Al.sub.4 B.sub.1-3 C.sub.4 ; AlB.sub.24 C.sub.4 and Al.sub.4 BC. The body is heated with the separate source of aluminum, such that at least a portion of the surface of the body is contacted by liquid or vaporous aluminum for a time and temperature sufficient to form the aluminum-boron-carbon abrasive article.
摘要:
Hard disk drive components, such as, sliders, load beams, support arms, actuators, actuator bearings, spacers, clamps, spindles, ball bearings, thrust bearings, journal bearings, base plates, housings, and covers, formed of a multi-phase ceramic-based material. One method of making the hard disk drive components includes (a) forming a porous body of ceramic; (b) infiltrating a liquid into the pores of the ceramic body; (c) solidifying the infiltrated liquid; and (d) machining the metal-infiltrated ceramic body to form the hard disk drive component.
摘要:
Subject boron carbide to a passivation treatment at a temperature within a range of 1350.degree. C. to less than 1800.degree. C. prior to infiltration with a molten metal such as aluminum. This method allows control of kinetics of metal infiltration and chemical reactions, size of reaction products and connectivity of B.sub.4 C grains and results in cermets having desired mechanical properties.
