DEPOSITION OF NICKEL ON CARBON FIBRES BY GALVANIC METHOD
Journal Title: Materials Engineering - Materialove inzinierstvo (MEMI) - Year 2012, Vol 19, Issue 1
Abstract
The investigation of coating parameters in quasi-static coating of Ni layer on carbon fibre tow by galvanic method is presented. The tow of fibres was immersed in typical galvanic bath based on NiSO[sub]4[/sub], NiCl[sub]2[/sub], Na[sub]2[/sub]SO[sub]4[/sub] and H[sub]3[/sub]BO[sub]3[/sub] and current to carbon fibres was supplied by two leading metal rolls which are parts of continuous coating apparatus. The main parameters were current of 1 A, electrolyte temperature of 50 °C and the distance from power contacts to level of galvanic bath (8 or 13 cm). The amount and structure of deposited Ni layer at coating time 15 and 90 seconds of exposure in electrolyte and depth of immersion of tow into bath were discussed.

34CrMo4 steel resistance against the SSC after controlled cooling process
The sulphide stress cracking corrosion resistance of 34CrMo4 steel after the accelerated cooling process under the Ar3 temperature was investigated. Two modes of heat treatment were applied to achieve homogeneous microst...
Interaction of sub-zero treated Cr-V ledeburitic steel with alumina,100 Cr6 steel and bronze in dry sliding
The interaction of the Vanadis 6 steel, processed without/with an application of sub-zero treatment, with alumina (hard counterface), 100Cr6-ball bearing steel (counterface of an intermediate hardness) and CuSn6 (soft co...
Cyclic plastic behavior and fatigue life of AZ91 alloy in as-cast and ultrafine-grained state
Fatigue properties of magnesium alloy AZ91 in as-cast and in ultrafine-grained state prepared by equal channel angular pressing were investigated. The fatigue strength in the low-cycle fatigue region was found to be subs...
The influence of heat treatment on properties of lead-free solders
The article is focused on the analysis of degradation of properties of two eutectic lead-free solders SnCu0.7 and SnAg3.5Cu0.7. The microstructures of the intermetallic compound (IMC) layers at the copper substrate - sol...
