Effect of Si and Al Additions to Steel on Machinability in Gear Cutting
The influence of Si and Al additions to 0.55 mass% C steel on machinability is discussed in cutting with a fly tool of TiAlN coated high speed steel, as performed in gear cutting. Three model steels are prepared with controlling nearly the same hardness to study the effects of the alloying elements: one reference steel with C as the only alloying element (Base steel), and two steels alloyed also with 1 mass% Si or Al. The cutting tests are performed to obtain the cutting forces, observe the cutting chips and analyze the damage on the rake faces of the tools. The orthogonal cutting data in the cutting force simulation are identified to minimize the discrepancies between the measured and the simulated forces for the tested steels. When cutting the Base steel, few adhered materials form and the coated thin layer is worn mainly by abrasion. When cutting the Si alloyed steel, the coating surface is covered by adhered layers containing Si–O, Fe 2 SiO 4 and FeO, which contribute to the lowest friction and protect the coated thin layer from wear. When cutting the Al alloyed steel, an Al 2 O 3 layer forms on the coating. The Al 2 O 3 layer induces high friction, large cutting forces and cutting heat, resulting in the rapid substrate softening and coating fracture.
期刊介绍:
The journal ISIJ International first appeared in 1961 under the title Tetsu-to-Hagané Overseas. The title was changed in 1966 to Transactions of The Iron and Steel Institute of Japan and again in 1989 to the current ISIJ International.
The journal provides an international medium for the publication of fundamental and technological aspects of the properties, structure, characterization and modeling, processing, fabrication, and environmental issues of iron and steel, along with related engineering materials.
