A Study of Intermetetallic Compound Growth in the Sn/Ni Couples(I) : Intermetallic Compound Formation and Growth Kineties
Journal of the Korean institute of surface engineering, volume 22, issue 1, 1989, Pages 3~9
The intermetallic compount formation, growth rections, and growth kinetices as functions of the aging temperaturess, time, and the condition of substarte have invedtigted in the Sn/Cu and Sn/Ni bimetal couples. The η'-phase (Cu6Sn5) and
-phase (Ni3Sn4) were only found to grow at 20 and
in the Sn/Cu and Sn/Ni bimetallic coples repectively. Above that temperatures, all other compounds were formed in sequence of high Sn content plase and the metastable Cu41Sn11 was formed at agend
. The ectivation energy for the growth of intermetallic compounds was 14.7Kxal/mole in the Sn/Cu interface and 26.7Kcal/mole in the Sn/Ni interface.
A study on the carburization of Fe-Cr alloys.
Journal of the Korean institute of surface engineering, volume 22, issue 1, 1989, Pages 10~16
The properties of carburization on Fe-Cr alloys at 900-96
were investiged. The study on carbide layer which had developed during solid-carburizing was made by use of S.E.M, E.PM.A, and X-ray analyzer. The results obtained were summarized as follows, the composition of carbide and the value of activation energy for the growth of carbide layer on each Fe-Cr alloy were 1) Fe-1Cr : M3C and 52Kcal/mole 2) Fe-3Cr and Fe-5Cr : M7C3and 85-88Kcal/mole 3) Fe-7Cr and Fe-9Cr : (M7C3+M23C6)and 55-66Kcal/mole.
Structural Characteristisrics and Adhesion of Chemicaly Vapor Deposited TiN Films on Stainless Steels
Journal of the Korean institute of surface engineering, volume 22, issue 1, 1989, Pages 17~25
The structural Charactesties and adhesion of chemically vapor deposited TiN film on stain less steels have been investated as functions of deposition temperature, surface roughness of sub state, and types of substrates. The grain zine and the lattice parameter of TiN film decreased with decreasing roughness of substates. The(200) preferred orientation was developed dominatly and the lattlice parameter decreased as temperature intereased reardless of the surdless roughnessand type of the substrates used. The surface morphology of TiN film changed from bushed crystal to a plate and then to pyamidal dense crystals with an increase in the deposition temperature. The adhesion of TiN films increased with coating thinkness and decreased with surface roughness in general. The calculations using a Bejamin & Weaver's model have been compard. Maximum valuse of adhesion energy calculated using Laguier's model were W304=331Jm-2,w410=113Jm-2,andW430=107jm-2
Effect of Spraying Conditions in Flame Spraying of Ni-Cr Base Self Fluxing Alloy on Mild Steel
Journal of the Korean institute of surface engineering, volume 22, issue 1, 1989, Pages 26~42
It has between investigated that the optimum spaying conditions, such as, spraying distance, fusing temperature and fusing time, ect, in a Ni-cr base self fluxing alloy sprayed on the mild steel substrate by oxygen-acetylenc flame spraying. Sprayed specimens on various conditions were fuused in a vacuum furnace and the results were as follows. The optimum spraying condition for excellent coating layer are obtained under spraying distances, fusing temperature and fusing and time ; 180~240mm,1050~110
and 15~30min, respectively. The adhesive strength and surface hurface hardness of the as sprayed specimens were very low by mechanical bonding becaus of the diffusion layer during process. The carbides and borides and formed in the sprayed coating layer and densification of the layer was resulted from the elimination of pores and oxides. The hardness of sprayed coating layer, particularly in the high temperature, was superior to ordinary tool steels.
A Study on Composite Electroless Nikel Plating with Ceramic Dispersive
Journal of the Korean institute of surface engineering, volume 22, issue 1, 1989, Pages 43~51
The characteristion of composite electroless Nikel palting on the condition of adding 3kinds ceramic dispersives, Al2O3, Si3O4 and artificial diamond powder were studied. Decreasing solution temperature for composite plating was required to depress the spontaneous decomposition caused by dispersive including enlargement of reaction surface. The rate of composite plating was faster than that of general electroless-Nickel plating without dispersive. this increasing tendency of plating rate was remarkable for the active catalysis, like diamond powder.
