Patent number: 4628002Abstract: This invention is directed to a surface treatment for SiC monofilament developed for the purpose of increasing the transverse strain-to-failure of composites, particularly aluminum composites. The surface treatment includes a fine grain SiC region adjacent to the bulk or stoichiometric SiC region and a transition region which interacts with the matrix material.Type: GrantFiled: May 28, 1985Date of Patent: December 9, 1986Assignee: Avco CorporationInventors: Raymond J. Suplinskas, Thomas W. Henze, James V. Marzik

Patent number: 4481257Abstract: Silicon carbide filament is produced by overcoating a carbon monofilament core using continuous process vapor deposition. The deposition takes place by passing the carbon monofilament through a reactor into which gaseous sources of silicon and carbon are injected. At a deposition temperature of about 2370.degree. F., a deposit of fine grained beta crystals of silicon carbide are formed. Application of a thin protective coating of boron-based refractory material on the surface of the silicon carbide filament both adds strength and provides a surface which is readily bonded to both metals and epoxy matrix materials during the casting of composite structures.Type: GrantFiled: June 17, 1983Date of Patent: November 6, 1984Assignee: Avco CorporationInventors: Raymond J. Suplinskas, Albert W. Hauze

Patent number: 4415609Abstract: The invention relates to a surface treatment for stoichiometric silicon carbide. A carbon-rich silicon carbide layer is applied over the silicon carbide. In the case of the silicon carbide surface, the ratio of silicon to carbon in the carbon-rich layer varies from one at the silicon carbide interface to near zero in the interior of the carbon-rich layer to greater than zero and preferably 0.3 to 0.5 on the surface of the carbon-rich layer remote from the interface. A preferred method of making the silicon carbide layer is also presented.Type: GrantFiled: May 5, 1982Date of Patent: November 15, 1983Assignee: Avco CorporationInventors: Harold E. Debolt, Raymond J. Suplinskas, James A. Cornie, Thomas W. Henze, Albert W. Hauze

Patent number: 4358473Abstract: This invention relates to a process control system and method of controlling a chemical vapor deposition (CVD) process where a coating is deposited on a substrate heated by passing a current through the substrate to create a heating zone. The control system relies on detecting a signal induced on the coated substrate outside of the heating zone and using the induced signal to control one or more process parameters.Type: GrantFiled: May 22, 1981Date of Patent: November 9, 1982Assignee: Avco CorporationInventors: Harold E. DeBolt, Joseph Morrissey, Raymond J. Suplinskas

Patent number: 4315968Abstract: Silicon carbide filament is produced by overcoating a carbon monofilament core using continuous process vapor deposition. The deposition takes place by passing the carbon monofilament through a reactor into which gaseous sources of silicon and carbon are injected. At a deposition temperature of about 1300 C., a deposit of fine grained beta crystals of silicon carbide are formed. Application of a thin coating of silicon-rich silicon carbide on the surface of the filament both adds strength and provides a surface which is readily bonded to metals, glass and resin matrix materials during the forming of composite structures.Type: GrantFiled: February 6, 1980Date of Patent: February 16, 1982Assignee: Avco CorporationInventors: Raymond J.
