دانلود کتاب Vacuum Technology: Practical Heat Treating and Brazing (06091)

Focuses on basic and practical issues A hands-on reference for those involved with vacuum technology Get real answers to everyday problems...information you wonAt find anywhere else. To fill an existing need within the vacuum industry, this hands-on reference book focuses on the basic and practical issues of vacuum technology...from startup to finished product. ItAs an everyday tool that provides information on maintenance requirements and cautions, actual case histories for oil-hardening and gas-quenching materials and sintering, details for special processes in vacuum, and advice for leak detection troubleshooting. Written by industry experts (whose collective knowledge and working experience will be difficult to match), this book walks you through many areas including: Theory of Vacuum Technology: Vacuum pumping systems, measuring vacuum levels Introduction to Vacuum Thermal Processing: Solution treatments (loading guides, vacuum levels, heating rates, outgassing) Vacuum Considerations for Heat Treatment: Residual gas and vacuum integrity, significance of vapor pressure, temperature considerations, etc. for most alloy groups Furnaces and Equipment: Basic selection criteria, furnace maintenance, special atmospheres, applications Work Preparation and Handling: Cleaning, fixturing, workpiece loading Principal Process Variables: Temperature measurement, workpiece temperature tracking, vacuum and atmosphere control, cooling and quenching control (integral liquid-quench furnaces, gas-quenching, etc. ) Vacuum Instrumentation and Control: Mechanical and electronic vacuum gages, helium leak detectors, the Quadrupole residual gas analyzer Temperature Control Systems: Temperature measurement and heat transfer, integrated control systems, temperature limit controllers Commercial Practice (for common metal systems): Heat treating & case histories Special Processes in Vacuum: Melting and casting, directional solidification, metal injection molding, surface enhancement Inspection and Quality Control: Types of pumps used in vacuum systems, vacuum measurement, leak detection and troubleshooting
