(ELSEVIER SCIENCE SA, 1998)Planar-randomly oriented alumina shea fiber (Saffil) reinforced Al-Si (LM 13) alloy metal matrix composites (MMCs) were produced by a modified liquid infiltration technique. The wear and friction behavior of LM 13 alloys ...
-
(INST MATERIALS, 1998)Metal matrix composites were produced with modified pressure liquid infiltration equipment using short delta-Al2O3 (Saffil) fibre preforms, containing 10, 15, 20, 25, and 30 vol.-% fibres as reinforcement and the alloy ...
-
(CARL HANSER VERLAG, 1998)The effect of copper addition in the range from 0 to 3 % on the tensile creep behaviour of gravity cast alloy ZA-8 has been investigated at a temperature of 120 degrees C and an applied stress of 40 MPa. It was found that ...
-
(KLUWER ACADEMIC PUBL, 1998)A combination of physical vapour deposition and plasma-assisted chemical vapour deposition techniques were used to deposit Cu-, Ni- and Sn-rich SnO/SnO2 coatings on metal and ceramic substrates. Cu and Ni were deposited ...
-
(SPRINGER, 1998)The dehydration and decomposition bauxite mixed with alkaline compounds were investigated under dynamic and isothermal conditions. Alkaline compounds (CaO or/and Na2CO3) were added to bauxite samples in various mole fractions ...
-
(ELSEVIER SCIENCE SA, 1999)Metal matrix composites (MMCs) were produced by a pressure infiltration technique, using Saffil (delta-Al2O3) alumina short fiber preforms as the reinforcement, and the alloy Al-12 wt% Si (LM 13) as the matrix material. ...
-
(ELSEVIER SCIENCE SA, 1999)This study reports on characterization of borides formed on impurity-controlled steels essentially containing 0.3% C, 0.20 P, 0.5% Cr; 0.3% C, 0.02% P, and 1.0% Cr. The formation of borides on the impurity-controlled ...
-
(KLUWER ACADEMIC PUBL, 1999)Ti-6Al-4V, that was explosively welded to a 304 stainless steel plate, was ion nitrided in a d.c. plasma. An effective nitriding was achieved due to the high dislocation density and vacancy concentration that emaneted from ...
-
(ELSEVIER SCIENCE SA, 1999)In this study, the corrosion behaviour of grit-blasted AISI 304L stainless steel substrates coated with Al2O3 was investigated in 1 N H2SO4 solution. Coatings were produced by employing a plasma-spray process. The phase ...
-
(ELSEVIER SCIENCE SA, 1999)The results showed that there are no certain transition lines between the bond layer, the cermet layer, and the ceramic layer. The SEM results indicated the presence of porosity, oxide, inclusion and unmelted particles. ...
-
(ELSEVIER SCI LTD, 2000)Surface preparation techniques such as plasma spraying, physical vapour deposition and chemical vapour deposition have been used to make convenient material combinations for the use in high-technology requirements. ...
-
(CARL HANSER VERLAG, 2000)In this investigation. an attempt has been made to examine the wear response of some modified zinc-aluminum based alloys and two conventional bearing alloys at the sliding speeds of 0.65, 1.30 and 1.90 ms(-1), over a range ...
-
(ELSEVIER SCIENCE SA, 2000)A series of experiments were performed to evaluate some properties of borided 99.5% purity nickel. Boronizing was carried out in a solid media consisting of Ekabor powders at 950 degrees C for 2, 4, and 8 h, respectively ...
-
(ELSEVIER SCIENCE SA, 2000)In aluminium die casting, tools are exposed to erosion, corrosion and soldering due to the frequent contact of the tool surface to the casting alloy, to heat checking and gross cracking due to thermal fatigue and to oxidation ...
-
(KLUWER ACADEMIC PUBL, 2000)An investigation was carried out on the kinetics of thermal decomposition of plumbo-jarosite. The kinetic models of dissociation of the compounds in the ore were identified. The results of the kinetic studies and the ...
