metalliding, vbl. n. Manuf.|ˈmɛtəlaɪdɪŋ|
[f. metallo- + -ide + -ing1.]
A form of electroplating in which the electrodes are immersed in a bath of molten fluoride salts from which metal ions diffuse into the cathode to form a surface layer whose composition varies continuously from the surface inwards.
1967Iron Age 22 June 71/1 Metalliding is a high temperature electrolytic technique in which an anode and a cathode are suspended in a molten salt bath. As a direct current is passed from anode to the cathode, the anode material diffuses into the surface of the cathode, putting on a uniform pore-free coating. 1971Corrosion XXVII. 55/1 Metalliding involves the electrolytic deposition of a variety of diffusion coatings on metal surfaces.
Hence (as a back-formation) ˈmetallide v. trans., to deposit by this process; ˈmetallided ppl. a.
1967Aviation Week 3 July 55/2 Metallided coating can also be produced from yttrium..and the rare earth elements. 1967Sci. News 15 July 66 Molybdenum, for example, is a relatively soft metal; when boron is metallided into it, the resulting surface alloy is apparently second in hardness only to diamond. |
