Equipment
Formation of coatings on the installation mikrodugovogo oxidation UMDO-1M by mikrorazryadov in the electrolyte, resulting in the oxide layer is created with the unique operating characteristics that are dependent on the process of technological regimes.
Installation consists of the technological power source, block management and galvanic baths. Installation can process the details of different measures to 1000h500h500 mm. When the current density up to 30 A/dm2, and a different time obrubotki.
Properties of coatings determined by DHS, their composition and structure, which were, in turn, depend on the material basis of electrolyte and the mode of processing. For DHS-coatings obtained on the aluminum spla islands, characterized by the following data:
thickness – up to 400 microns
microhardness – up to 25 GPa
critical voltage – up to 10 000
heat resistance – withstands thermal shock to 25000S
corrosion resistance – 1-th point on the scale desyatiballnoy
durability – at the level of hard alloys
porosity – from 2 to 50% (adjustable)
Main advantages: High surface properties compared to conventional anodizing. Environment, on the universality, as well as the lack of need careful advance preparation of treated surface at the beginning of the technological chain.
