Hot Corrosion of Fe-Cr-Si and Fe-Cr-Pt alloys in Molten Salts.
Journal of the Korean institute of surface engineering, volume 27, issue 1, 1994, Pages 3~11
Cyclic hot corrosion studies have been carried out on(82~94) wt. % Fe-(5, 10, 15) wt. % Cr alloys con-taining either (1, 3)wt. % of Si or Pt as minor alloying elements in molten salts of(
+NaCl) between 820 and
. Si or Pt decreased corrosion rate with the most pronounced effect being observed for alloys having 15wt. %Cr. Especially, as Si or Pt contents are increased from 1 to 3 wt. %, improved corrosion resistance was obtained. The beneficial effect of Si addition is due to the presence of the Si-rich second phase along the grain boundaries as well as the formation of the protective
layer between substrates and oxide scale. The Pt addition also increased the corrosion resistance by enhancing the formation (
+layers and by increasing the adherence of the oxide scale.
The heat treatment characteristics of plasma sprayed ZrO
Journal of the Korean institute of surface engineering, volume 27, issue 1, 1994, Pages 12~18
The plasma spray process was used to deposit coatings of
-8wt%Y2O3 powders on mild steel sub-strate, and the characteristics of as-deposited and heat treated coatings have been investigated. Particulary, the variations of porosity, wear resistance, thermal barrier and thermal shock resistance in
coatings after heat treatment under vacuum circumstance have been investigated. The porosity of the coating layer was increased with increased spray distance. In the case of the arc current of 450A and at the spray distance of 50mm, it was obtained the lowest amount of porosity. After heat treatment, the amount of porosity was found to be decreased, and the wear resistance, microhardness and thermal shock resistance were im-proved. However, the thermal barrier was decreased.
A Study on the Adhesion Property of Al-Cr Alloy Films by Evaporation
Journal of the Korean institute of surface engineering, volume 27, issue 1, 1994, Pages 19~28
A study on adhesion property of evaporated Al-Cr films was conducted on steel sheet by using two-source evaporator. Adhesion of Al-Cr coated steel was evaluated by tape test after
bending. Adhesion was decreased with increasing the Cr content in Al-Cr films. It was thought that the decrease in adhesion with increasing Cr content be related to insufficient wetting and diffusion of Cr atoms in the film. Best adhesion was achieved in the case of pure aluminum film..
The Effect of Titanium and Copper Coatings on the Modulus of Rupture of Alumina
Journal of the Korean institute of surface engineering, volume 27, issue 1, 1994, Pages 29~35
The effects of coating of 3
thickness on the mechanical property of alumina after heat treatment at 100
for 30minutes under
torr vacuum was quantified in terms of modulus of rupture(MOR) using Weibull plot. While the copper coating did not change MOR of alumina due to the nonwetting behavior of Cu on
, the reactive titanium metal coating caused a noticeable 29% reduction in averaged MOr strength. This was related with the combined effects of microcracks in coating formed during heat treatment and good bonding character between Ti and
. The effect of cosputtering of Ti and Cu, bilayer coatings of Cu/Ti and Ti/Cu were also investigated. It was found that Ti, cosputtered, Cu/ti and Ti/Cu coatings reduced MOR strength of alumina in the order listed. This was correlated with the amount of Ti at coating/alumina inter-face associated with a coated layer or segregation of Ti during heat treatment.
A Study on Wear Resistance of TiN Films Prepared by Arc Vapor Ion Deposition Process
Journal of the Korean institute of surface engineering, volume 27, issue 1, 1994, Pages 36~44
The TiN films were deposited on the stainless substrates using arc vapor ion deposition process to in-vestigated the wear resistance. Pin-on-disc tests were performed to measure the volume wear loss of TiN films. The substrate bias voltages and nitrogen flow rates were selected as the deposition parameters of TiN films. It was found that the wear resistance of TiN films was enhanced with increasing bias voltages(0~-300 V) and nitrogen flow rates(220~380 SCCM). The volume wear loss TiN films were about 9.5~2.1
with bias voltages and nitrogen flow rates, respectively.
A Kinetic Study on the Electrodeposition of Zn-Fe Alloys
Journal of the Korean institute of surface engineering, volume 27, issue 1, 1994, Pages 45~53
A kinetic study on the electrodeposition of zinc-iron alloys onto a steel in chloride solutions has been car-ried out using a rotating disc geometry. The results show that the deposition rate was increased with electropotential, disc rotation speed and temperature, and consequently the rate was partly controlled by elec-trochemical reaction and partly by mass transport. The iron content of deposit was more increased with cell voltage than with disc rotating speed and temperature. During electrodeposition process, the addition of metal-lic zinc powder retards oxidation rate of
