Final part of the publications review devoted to microarc discharge oxidizing (MDO) in electrolytes-suspensions in relation to objects of medical appointment. The estimates of morphological parameters of the surfaces modified in electrolytes-suspensions and also data of the modified surfaces researches by electronic microscopy, the EDS-analysis, potential-dynamics polarizing tests are given. Experience of corrosion resistance increase of implants from magnesium alloys by formation on them a porous MDO-layer and the subsequent saturation it with the TiO2 sol-gel covering is described. Results of the researches carried out by authors concerning of ultradisperse diamond powders (UDA) additives to silicate and alkaline electrolytes influence on characteristics of MDO-coverings are presented. This modifying is capable to expand essentially borders of application of metals and alloys in medicine, biology, technologies of live systems.
