ASPECTS OF UTILIZATION OF SINTERED BASALT PARTS IN MACHINE BUILDING

Experimental wearing tests with parts from sprinklers, harvesters, cereal, hay and straw gathering machines demonstrated that the use of sintered basalt in machine building contributed to a twofold-threefold decrease of energy, brass, graphite, cast iron and aluminium consumption, along with much steadier technological quality indices. The diffraction lines of natural rocks and, then, those of sintered basalt parts were analysed using diffractometric investigation methods. The diffractograms examined verified the factors that contribute to the wear resistance modification, and the necessity of varying the technologies for shaping and mechanical processing of parts in connection with calcination and sintering heat treatment
