Formation of Mo(Si,Al)2 Coating on Surface of Mo Thin Plate by Dip-coating Technique Using Al-25mass%Si Liquid at 1073K

SrBi2Nb2O9 Thin Films Deposited by Dip Coating Using Aqueous Solution

A new approach for SrBi2Nb2O9 (SBN) thin ®lms synthesis using aqueous solution was successfully experienced. The deposition solution was prepared from Sr±Bi±Nb mixed-citrate solution, requiring no special atmosphere and using common reagents. Films were deposited by dip coating onto Pt/Ti/SiO2/ Si(100) substrates and heat treated at temperatures ranging from 300 to 700 C. The process of formati...

Effect of Unfired Tape Porosity on Surface Film Formation by Dip Coating

Thin ceramic layers have been fabricated by dipping green tapes of alumina, formed by the doctor-blade casting method, into aqueous slurries containing mixtures of alumina and either unstabilized zirconia (MZ–ZrO2) or mullite. It was observed that the formation of a thin layer on the surface of the tape is governed by both liquid entrainment and slip-casting mechanisms, and was accelerated by i...

Tin-doped indium oxide thin films deposited by sol–gel dip-coating technique

Indium tin oxide (ITO) thin films were prepared by the sol–gel dip-coating (SGDC) technique. The microstructure and electrical properties of ITO thin films crystallized using rapid thermal annealing (RTA) were compared with those of films prepared by classic thermal annealing (CTA). ITO thin films were successfully prepared by CTA at 500 jC for 30–60 min. At the same temperature of 500 jC and w...

A Model for Dip-coating of a Two Liquid Mixture

Kinetic Study of Niobium Carbide Coating Formation on AISI L2 Steel using Thermo-Reactive Deposition Technique

In the present study, Thermo-Reactive Deposition method (TRD) in a molten bath was used to form niobium carbide coating on AISI L2 steel. The coating was formed in five different composition of borax (Na2B4O7), boric acid (B2O3), and ferro-niobium. For all of the five compositions of molten bath, niobium carbide coating treatment was carried out at 1173 K, 1273 K, and 1373 K for 2, 4 and 8 hour...
