Structural characterization of laser-treated Cr3C2–NiCr coatings
The interconnected porosity of the Cr3C2–NiCr coatings obtained by high-velocity oxy fuel spraying is detrimental in corrosion and wear resistance applications. Laser treatments allow sealing of their surfaces through melting and resolidification of a thin superficial layer. A Nd:YAG laser beam was used to irradiate Cr3C2–NiCr coatings either in the continuous wave mode or at different repetiti...
متن کاملHandling and Co-firing of Shredded Municipal Refuse and Coal in a Spreader-stoker Boiler*
A system for handling up to 120 tons/day of municipal refuse has been developed for co-firing with coal in a spreader-stoker boiler at the Colum bus, Ohio, Municipal Electric Plant. This system is unique in that the refuse has undergone only shred ding to 90 percent minus 4 in. (10 cm) and magnetic separation of ferrous material. The refuse-handling system comprises: (1) a push-pit with a hyd...

15 صفحه اولThermal Spray Coatings
THERMAL SPRAY is a generic term for a group of processes in which metallic, ceramic, cermet, and some polymeric materials in the form of powder, wire, or rod are fed to a torch or gun with which they are heated to near or somewhat above their melting point. The resulting molten or nearly molten droplets of material are accelerated in a gas stream and projected against the surface to be coated (...
