摘要:
A hard drive disk substrate is formed of a multi-phase ceramic-based material having at least two phases with amorphous phases being present in an amount less than about 1 volume percent based on the volume of the ceramic-based material or at least one phase being free metal. A process for producing the ceramic-based disk substrate is produced by forming a flat disk of a porous ceramic and then infiltrating the porous ceramic with a metal whereby a multi-phase ceramic-based computer hard drive disk is produced. Additionally, a step of passivating the porous ceramic by elevating it to a temperature of about 1300.degree. to about 1800.degree. C. before the infiltrating step may be performed, such that the surfaces are passivated and the reaction kinetics can be controlled during the infiltrating step. A preferred composite material is made of a multi-phase boron carbide composite material including grains having peaks with an average roughness value, Ra, of between about 1 to about 200.ANG., the roughness value being formed in situ by causing a micro hardness gradient of between about 19 and about 3200 Kg/mm.sup.2 in the various phases of the multi-phase boron carbide composite material.

摘要:
A golf club with a multi-material face is disclosed herein. More specifically, the golf club head in accordance with the present invention has a striking face that forms a pocket, wherein the pocket is filled with a secondary material having a lower density to improve the performance of the golf club head. The multi-material face disclosed in accordance with the present invention may generally have a characteristic time slope of greater than about 5 and less than about 50, wherein the characteristic time slope is determined based on the various data points collected according to the United States Golf Association's (USGA's) Characteristic Time (CT) test.

摘要:
A golf club that utilizes multiple materials to achieve improved performance is disclosed herein. More specifically, the present invention relates to a golf club that utilizes different materials to construct different portions of the iron type golf club head allowing weight to be removed from portions of the golf club head that doesn't require such weighting. The current invention utilizes a lightweight material to form a blade portion of the golf club head while utilizing a standard steel material to form the hosel portion of the golf club head to allow the malleability characteristics of a golf club head to be maintained. The weight saved from the lightweight material used to create the blade portion can then be used to create a sole insert that is made out of a dense and heavy material to improve the CG and MOI characteristics of the golf club head to dramatically improve the performance of the golf club head. The current invention's usage of the multiple materials allows the performance of the golf club head to be increased without sacrificing the feel characteristics of the golf club head.

摘要:
A golf club head with an improved face insert is disclosed herein. More specifically, the present invention discloses a golf club head wherein the face insert has a cavity near the top surface of the face insert that extends vertically downward towards the bottom surface of the face insert while terminating short of the bottom surface. The face insert having the cavity serves to remove unnecessary weight from the upper surface weight of the face insert; while the cavity that terminates short of the bottom surface yields a solid face insert near the bottom surface to preserve the structural integrity of the face insert where the golf club head impacts a golf ball. The cavity created within the face insert may be filled in with a lightweight material that helps further maintain the structural integrity of the entire face insert while still removing unnecessary weight from the face insert.
