• MICRO: Product Extras (June '2000)
  a surface region with high wear resistance. According to Poco Graphite, Pyrograph generates fewer particles than comparable materials and coatings. In beta site tests and evaluations by both semiconductor fabs and OEMs, the. MICRO: Product Extras (June '2000...
• Laser Machining Fiber-Reinforced Plastics
  reinforcement. Less commonly, the term graphite-reinforced plastic is also used. FRP is becoming increasingly common in small consumer goods as well, such as laptop computers, tripods, fishing rods, racquet sports frames, stringed instrument bodies, classical guitar strings, drum shells etc. Microsoft...
• A recipe for A Slick Design
  types or combinations of low-friction lubricants can be dispersed in the coatings to influence mechanical properties. For example, PTFE gives the lowest friction coefficient at 0.02. While moly-disulfide (MoS2) based coatings have the highest loadcarrying capacity. And graphite filled versions can...
• Empowering Proper Selection of Motor Technology
  to rotate the rotor. As the rotor turns, the current in the windings is. commutated, or switched, to produce a continuous torque output. 2. Conventional brush-commutated DC motors use brushes (typically graphite with metal. content) as part of the commutation process, while brushless motors achieve...
• Empowering Proper Selection of Motor Technology
  , or switched, to produce a continuous torque output. Conventional brush-commutated DC motors use brushes (typically graphite with metal content) as part of the commutation process, while brushless motors achieve commutation electronically via a permanent-magnet rotor, wound stator, and rotor-position...
• Performance Characteristics of a Newly Developed Machinability Additive for PM Applications
  (Inco. 123Ni), natural graphite (Asbury Graphite SW-1651) and lubricants (amide wax and Zn-St) to make. premix samples. The chemical composition of each premix is shown in Table 1.

• Motor Type Selection
  . friction losses of maxon motors are included in the. permissible continuous torques of the motors. The friction. losses of the graphite brushes and the iron losses of. brushless EC motors depend on speed. The result is a. visible rounded boundary of their continuous operating. range. The motor must...
• High Rate and High Efficiency Hydrogen Generation via Water Electrolysis Catalyzed by Nano Powders (.pdf)
  is highly efficiency. For example, at 1 mA/cm2. two graphite electrodes run at 90% EE in half cell tests. Typical electrolyzers today run from 10 to. !. a few hundred mA/cm2. This rate necessitates large units to produce usable quantities of hydrogen. in practical time frames. Our target is to be as high...

• Magnesium Anodizing
  polypropylene material or low carbon steel (providing it is also used as the. cathode) can be used for the anodizing tank material for the acid-based magnesium. anodizing processes, while stainless steel tanks can be used for the alkaline magnesium. anodizing processes. Graphite and low carbon steel...
