Binary and multicomponent alloys, comprising such additives as tin, aluminum, lead, beryllium, silicon, chrome and others, including zinc being not the main alloy additive, are called bronzes. Depending on the main alloy additive there are different types of bronze – tin bronze, leaded bronze, silicon bronze and others.
Aluminium bronze is applied in manufacturing of load carrying parts for operating at high temperatures under conditions of high wear and corrosive action. For instance, it is used to produce gearwheels, bushings, friction gears, cocks, parts of water and steam turbines.
Tin bronzes comprising zinc and lead are used for casting of intricate pieces, including, in particular, art castings. Bronze with 9–10% tin is considered to be one of the best antifriction materials and is used for bearing manufacturing. Silicon bronzes are recommended as a substitute for tin bronzes and, in some cases, can replace expensive beryllium bronze.
Performance of bronze electrolyte-plasma treatment and polishing:
Recommended processing time for bronze polishing — 180 sec.
Grinding and deburring speed - 25 sec.
Average time to reduce the roughness value by 1 class - 75 sec.
The number of polishing cycles before changing the electrolyte - 60.
