A method for forming a transmission synchronizer friction surface includes the steps of forming a woven substrate fabric, oxidizing the substrate fabric, carbonizing the substrate fabric, densifying the carbonized substrate fabric, burnishing the densified carbonized substrate fabric, applying a thermoset adhesive to the burnished substrate fabric, and heating and pressing the piece of fabric against a conical surface of a synchronizer element. To form the fabric, yarn is formed of chopped substrate fibers, and the yarn is woven to form the woven substrate fabric. Densification is increased by extending a period of time of chemical vapor deposition to achieve a weight in an unburnished condition of at least 16 ounces per square yard for a thickness range of approximately 40 to 50 mils. Both sides of the substrate fabric are burnished. The material is pressed against the conical surface under a high pressure of at least 2000 psi to achieve the desired bonding of the substrate fabric to the conical surface.

A system and method for producing material characteristics are described. A magnetic treatment chamber with a high magnetic field treats workpieces; and a conveyor or transporter continuously moves the workpieces through the high magnetic field in the magnetic chamber. A frictional or mechanical engagement system extracts the workpieces through and out of the high magnetic field.

A process for making silicon powder or articles of manufacture such as an internal combustion engine valve by comminuting a homogeneous water-base slurry of silicon powder and at least one nitriding agent and permitting the slurry to chemically react for a time sufficient to enable the chemical reaction to substantially reach completion, then reducing the water content sufficiently to form a powder or an article and thence nitriding the article or powder by continuously varying the temperature over the range of 1000. degree. C. to 1450. degree. C. using a nitriding gas comprising nitrogen, hydrogen and helium and maintaining a constant nitriding gas composition throughout the nitriding cycle.

Method of manufacturing a helical gear allowing strategic placement of a hardenable wear-resistant and high strength layer at predetermined locations on the gear. The method includes the steps of forming a gear core preform having the general shape of the helical gear and positioning the gear core preform within an elastomeric mold having the specific shape of the helical gear. The method also includes the steps of filling the mold at the predetermined locations with the hardenable metallurgical material and densifying the gear core preform and the metallurgical material. Lastly, the method also includes the step of heat treating the densified gear core preform and metallurgical material, to obtain the helical gear having a wear-resistant layer at the predetermined locations. A helical gear formed according to method is also provided.

A process for preparing a nitridable silicon-containing material, which process includes (a) comminuting a slurry of silicon powder, water, at least one densification aid, including Al. sub. 2 O. sub. 3, and another densification aid, the comminuting performed to cause substantial chemical reaction between the silicon and the water; and (b) reducing the water content of the reacted slurry to form a dry mass. In another embodiment, at least one nitriding agent may be added to aid any nitridation which may be performed.
