Abstract
Variable property deposit, at least partially of fine-grained metallic material, optionally containing solid particulates dispersed therein, is disclosed. The electrodeposition conditions in a single plating cell are suitably adjusted to once or repeatedly vary at least one property in the deposit direction. In one embodiment denoted multidimension grading, property variation along the length and/or width of the deposit is also provided. Variable property metallic material deposits containing at least in part a fine-grained microstructure and variable property in the deposit direction and optionally multidimensionally, provide superior overall mechanical properties compared to monolithic fine-grained (average grain size: >20 micron) or entirely amorphous metallic material deposits.
