  • Effects of Joint Clearance on the Capillary Rise of a Molten Filler Metal
    in brazing is. the capillary force also known as capillary action. The. goal of this bulletin is to analyze the effects of joint. clearance on a capillary rise of a molten filler metal.
  • Osmotic Action and its Consequences (.pdf)
    action only. Hydrostatic pressure and capillary action are not part of this analysis because most coating - adhesion failures are clearly attributed to osmotic action.
  • Vacuum Brazing of Aluminum Cold Plates and Heat Exchangers
    metal. The filler metal, also known as a braze alloy, is drawn into the closely mated parallel surfaces of the aluminum plates by capillary action. The attributes of the vacuum brazing process include uniform heating, tight temperature control, no post cleaning processes, and process repeatability.
  • Seven Steps to Successful Brazing
    choice. The second major consideration in joint design is joint clearance, i.e., the distance between the faying surfaces. Because brazing works through capillary action and joint clearance defines the capillary, this is a critical consideration. For most brazing alloys in the B-CuP and B-Ag families
  • When Brazing Beats Welding
    in that the temperature is considerably lower and does not melt the base metals. Rather, the heat source melts a filler metal and draws it into the joint by capillary action. It creates a metallurgical bond between the filler metal and part surfaces. Like welding, joint strength often exceeds that of the individual
  • Porous-Metal Bearings
    the loaded zone of the bearing is reabsorbed by capillary action. Because these bearings can operate for long periods without additional lubricant, they can be used in inaccessible or inconvenient places where relubrication would be difficult. Adding from 1 to 3.5% graphite frequently enhances
  • IMTS Aims at Honing the Competitive Edge
    machining techniques. According to Univ. of Florida researchers, it produces nanoscale, mirror-finish surfaces on capillary tubes, bent tubing, and other free-form parts. And engineers at will showcase developments such as rotating turning tools that spin as
  • Sponge wrings cost from MR-fluid devices
    these concerns. Here, capillary forces hold a small amount of MR fluid absorbed in a porous matrix material. Such devices require much less fluid than conventional types and need no seals, bearings, and other high-precision parts. The approach could make feasible cost-sensitive applications including
