“…Recognized importance draws extensive attention of researchers [1][2][3] where the investigated aspects can be grouped into studies of morphology of worn out tools, chemical stability of tool materials, aspects of strength, etc. Severity of tool wear as a whole depends on the intensity of individual wear mechanisms or their combinations.…”

AbstractThe paper is aimed on identification and characterization of wear mechanisms of SiC whisker reinforced alumina when turning aged Alloy 718 under different cutting conditions and when machining dry and with coolant. Secondary and back-scatter electron microscopy accompanied by focus ion beam milling and EDX techniques were used for analysis of worn-out tools. Notch wear on the major cutting edge was found to consist of two notches: depth-of-cut notch and secondary notch located outside the chip area. The last was found to be governed by adhesion and attrition associated with adverse chip flow conditions. Formation of minor notch was related to attrition by the defects found on the machined surface. Diffusion of Ni, Fe and Cr into SiC whiskers was found to degrade them and facilitate adhesion. Chemical wear mechanisms were found to be responsible for degradation and decomposition of whiskers and formation of tribolayer on tool surfaces, which in turn was related to the reduced adhesion of Alloy 718 on the tool. Cracking on the tool rake and localized plastic deformation were found to further accelerate tool deterioration.

“…Other ceramic-type tools include sialon (Si 3 N 4 -Al 2 O 3 ), Al 2 O 3 reinforced with silicon carbide whiskers (SiC w -Al 2 O 3 ), cubic boron nitride (CBN), and polycrystalline diamond (PCD). These materials have been investigated [7][8][9][10][11][12][13][14][15] in the machining of various hard work materials and are generally believed [2,16,17] to last significantly longer than carbides under certain conditions. Sialon and SiC w -Al 2 O 3 have become particularly popular with superalloys.…”

This study examines the performance of a new class of wearresistant but economical cutting tools produced by varying the binder composition of standard cemented carbide composites. By replacing some or all of the cobalt binder with rhenium and nickel-based superalloy, a stronger composite tool results, potentially capable of machining heat-resistant superalloys at significantly higher cutting speeds.Sample tools with alternative binder were produced and compared to standard tools bound with cobalt only. Turning experiments on Inconel 718 were run to evaluate wear resistance and tool life for several grades. The experimentation also examined the effects of varying the relative proportions of each binder constituent as well as the overall binder percentage in the composite. Results show a clear advantage of the alternative binder tools as evidenced by a 150% increase in tool life or the equivalent of an 18% increase in cutting speed. Although increasing amounts of rhenium in the binder show a positive effect on performance, the effects of superalloy and overall binder % are inconclusive.
