Materials for Surface Protection of Heating Boiler Tubes

Аннотация

Certain properties of melted basaltic and clayey materials as well as compositions based on them for obtaining wear- and corrosion-resistant coatings for the tubes of steam boilers in thermal power plants [TPP] are studied. It is shown that melted mineral raw material can be used in compositions with liquid glass in developing protective coatings. Materials based on melted pyroxene wastes with the addition of basaltic fiber, whose weight content does not exceed 50%, possess the highest chemical stability and wear resistance.
