The information is given about small-sized equipment for producing sprayed powders of alloys based on copper and aluminum, intended for strengthening new and restoring worn-out surfaces by applying a gas-flame coating, as well as for the protection of parts against corrosion, process modes and powder properties. The high quality of the coatings obtained with the use of manufactured powders has been confirmed.

Aeriation of culture media with powder dispersers when cultivating yeast cultures during milk whey processing
The characteristics and structure of aerators based on titanium powders have been given, as well as the information about the effectiveness of their application when cultivating yeast cultures during milk whey processing.
The process of producing powder permeable materials made of spherical bronze powders by tin-phosphorous pressing method has been investigated. A technique for producing experimental samples based on the granulation of powders by a pore-former has been described. The technology is simple to carry out and it does not require complex equipment. Products have a satisfactory set of properties.
