摘要:This paper deal with the effect of Ag-Cu plating and Al hot dipping technology onthe performance of 1Cr18NigTi-ZL101A bimetal castings. The result show that optimum bimetalcastings can be made by electroplating and controlled Al hot dipping technology. The thickness ofbimetal layer is 0. 008 ~0. 015 mm, Shearing strength is 68. 6~84. 3 MPa.
摘要:The high temperature permeability of the coating material is one of the most important working properties. In this paper, a simple but accurate method is introduced. When the compressed air is passing through the sample with constant pressure, the flow of gas is measured atdifferent tempratures during the burning and escaping of the evaporative pattern, then, the permeability value can be obtained by conversion.
摘要:A discussion is made based on the mechanism of removing H in inside and absorbingH on surface of molten aluminium, and that leads to prove that high efficiency of dehydrogenationcould be obtained by spinning nozzle technology.

摘要:With the help of Chromatography, the median gases between Mg alloy and thegraphite sand mould were analized. Through the investigation on the surface film of Mg alloy, themechanism of the anti-burn behaviour of Mg alloy due to graphite sand casting was discussed.
