Porous composites on the basis of bi-polymer of natrium-carboxymethylcellulose containing aluminum powder and nano-particles of aluminum oxohydroxide have been developed. With the help of electronic microscopy the sizes of the formed pores were defined: 600 – 1000 μm; the surface porosity of the coating was defined as well, it made 65%. Using methods of x-ray diffraction analysis and infrared spectroscopy it was stated that the phase composition of porous composites remains unchanged in the process of forming. The possibility to form antifriction coatings by filling porous matrixes with solid lubricants is shown on the example of molybdenum disulfide. When applying the coatings to steel surfaces the friction coefficient reduces by 60%. With the help of differential scanning calorimetry the limit of coatings thermo destruction was defined: 300 - 306°C
