The properties of conversion coating on magnesium can be closely related to its microstructure and composition. This study investigated the evolution and microstructure of phosphate/permanganate conversion coating on AZ31 magnesium alloy. Results show that increasing the solution temperature reduced the growth rate of the coating. The temperature effect lies in the different structure associated with the coating layer contacting the substrate: a porous layer mainly composed of magnesium, aluminum hydroxides/phosphate formed in the solution at 40°C, while a compact magnesium oxide layer formed in the solution at 80°C. The formation mechanism of phosphate/permanganate coating was discussed in detail, with emphasis on the effect of the solution temperature.

The properties of nickel-phosphorus (Ni-P) electrodeposits can be best related to their phosphorus content and microstructure. This study systematically investigated the microstructural evolution and mechanical properties of the deposits plated from nickel sulfamate baths containing

Experimental results indicate that coarse nickel grains were substantially refined with the incorporation of phosphorus into the deposit. For example, as the deposit phosphorus content was increased from <mml:math display="inline"><mml:mrow><mml:mn>0</mml:mn><mml:mspace width="0.3em"></mml:mspace><mml:mtext>to</mml:mtext><mml:mspace width="0.3em"></mml:mspace><mml:mn>14</mml:mn><mml:mspace width="0.3em"></mml:mspace><mml:mi>wt</mml:mi><mml:mspace width="0.3em"></mml:mspace><mml:mo>%</mml:mo></mml:mrow></mml:math>0to14wt% , the structure of the deposit changed in sequence from a coarse column to a mixture of column and lamella, followed by a well-defined lamella, and finally to a homogeneous amorphous matrix dispersed with nanosized grains. Accompanied with this structural evolution, the deposit exhibited a distinct change in deposit hardness and internal stress. These properties and microstructure relationships are discussed in terms of the lattice defects in the grains and proton discharge during electroplating.1 January 2005 in Electrochemical and Solid-State Letters

Surface quality, geometry confinement, internal integrity, and mechanical properties are of great importance for the applications of microstructures fabricated by localized electrochemical deposition. This study shows that the copper microcolumn grown by resuming the anode and cathode to a given separation when the short-circuit contact occurs exhibits a nodular structure with microvoids residing on the nodular boundaries. Both the nodular structure and voids affect the apparent Young’s modulus of the microcolumn. A deposition-detection-withdrawal control method, which totally avoids the short-circuit contact, is thus developed to grow the microcolumn with improved geometry confinement and internal integrity.
