| Popis: | 1. Diffusion aluminizing sharply increases (300\2-600%) the thermal stability of heating equipment and machine parts of carbon steels, particularly rolled sections. 2. Our results failed to confirm the reported effectiveness of substituting aluminized carbon steel parts for heat-resisting steel parts in heating equipment. The carbon steel parts were put out of commission by severe warping resulting from reduced strength. 3. Heat-resisting steels can be replaced with aluminized carbon steels only in the case of parts not subject to mechanical loading. 4. Aluminizing is not expedient for parts made of heat-resisting chromium-nickel steels intended for prolonged operation at high temperatures because the aluminum gradually diffuses into the depth of the piece, which sharply reduces the aluminum concentration in the surface. |
