Abstract:
A femoral stem for canines or humans is made bone-compliant by use of a thick sintered titanium body in a proximal bone contacting region and a polymeric or ceramic body in a distal bone contacting region of the femoral stem. An elastic modulus is thereby engineered to match that of bone tissue. The porous sintered titanium body is created by sintering spheres of titanium. It is bonded to a central solid biocompatible metallic body by diffusion bonding. The distal region has a biocompatible polymeric body or biocompatible cement body. When compression molded the distal region develops an elastic modulus matching that of bone tissue. The proximal region has a porosity designed to encourage bone ingrowth.
Abstract:
The present invention relates to a method for manufacturing a dental scaler tip using a powder injection molding process which can produce the article in large quantities to save the manufacturing cost and forms an eccentric discharge port of a scaler tip to operate the mould using only one core pin, a mould used for the same that is provided with slide cores having the various shapes machined according to the article to enable the uniform article to be manufactured rapidly to enhance a characteristic and design of the article, and a scaler tip manufactured by the same that is more excellent in shape-reliability and injects fluid to a front end thereof along a curved section of the tip section to perform effectively an operation. In order to embody the above structure, the method for manufacturing a dental scaler tip consisting a coupling section mounted to the equipment and having a fluid passage formed therein and a curved shaped tip section extended from the coupling section, through a powder injection molding process, comprises the steps of preparing feedstock for injection by means of mixing raw material powder for the powder injection molding process containing titanium (Ti) or stainless steel with high molecular binder; and injecting the feed stock into a mould to form a molding body, wherein, the mould comprise an operating section to which cylindrical shaped core pins having multi steps and an eccentric end formed at a front end thereof for forming the fluid passage of the scaler tip is mounted; and a pair of slide cores disposed for supporting the eccentric ends of the core pins such that the slide cores face to each other and are slid in the direction perpendicular to the movement direction of the core pins to form a cavity corresponding to a shape of an article to be formed by an injecting process.
Abstract:
A method of manufacturing a tool body of a cutting tool comprises mechanically shaping the tool body to provide a metal surface on the tool body having a first surface characteristic. Thereafter, the metal surface is chemically treated with a metal reactant to create a relatively soft metal film along the metal surface. This soft metal film is removed via burnishing or other appropriate action to smooth the metal surface. After the surface is smoothed, the metal surface is then roughened to prepare the surface for the receipt of tungsten disulfide. The roughened metal surface is coated with tungsten disulfide. A cutting tool is disclosed that comprises a tool body defining a substantially isotropic surface having pits formed therein, and tungsten disulfide particles filled into the pits.
Abstract:
The aim of the invention is to provide a method for producing sintered components of sufficiently good strength. To achieve this, in a first step of the method, sinterable material is introduced into a first die and in a second step is compressed into a green compact. In a third step, the green compact is at least partially further consolidated in a second die and in a fourth step, the consolidated green compact is sintered. The density of the green compact achieved by the further consolidation undertaken in the third step is approximately 2 to 40 % greater than the density prior to said consolidation.
