“…The value of the element Cr diffused to the flank surface homogeneously depends on the preheating temperature, which increases the solubility of Cr atoms in M3C and causes lattice distortion, but part is the transformation into M7C3 with better hardness as described in related studies [78]. There is also an increased Nickel value on the flank surface, hence the CrNi which is designed to harden during cooling in the mold at the same time the carbide picks up some Cr and turns into M3C with the same morphology and increases hardness [79].…”

Ductile Iron has been used many times for the manufacture of components by casting, one of them is gears. The gear manufacturing method is one of the determinations of gear performance in service life. Wear and contact fatigue are important cases to consider during gear operation and the cause is surface hardness and dimensional accuracy. The purpose of this study was to investigate the surface behavior and gear profile dimension accurately. Gear chilled casting using an open mold made of silica sand. The chill will be coated to the surface of the mold wall then pouring at a temperature of 1400oC. Chill creates a good cooling rate on the surface to form FeC3 and M7C3 and (FeCrC)7C3, then produce a hardness of 700-994.96HV. Using chill thickness is 0.4mm, the dimensional accuracy of tooth thickness, pitch circular, and addendum circle diameter is very precise after the finishing process.

The wear interaction of cementite and pearlite in the white cast iron (WCI) was investigated using the two-body abrasive wear test under contact loads of 20, 35, and 50 N. The wear behavior, wear surface morphology, sub-surface structure, and wear resistance were evaluated using X-ray diffraction, microhardness testing, and nano-indentation. The results indicated that when the Cr content was increased from 0 to 4 wt%, there was a significant increase in the microhardness (H) and elasticity modulus (E) of the cementite. This yielded a 15.91%- and 23.6%-reduction in the degree of wear resistance and surface roughness, respectively. Moreover, no spalling and breaking of cementite was observed with increasing Cr content during the wear process, indicating improved wear resistance of the bulk cementite. In addition, the hard phase (cementite) and tough matrix (pearlite) composite structure exhibited a good protective and supporting effect. Thus, it was concluded that the interaction mechanism of the wear phase contributed to the reduction of the wear weight loss of the composite during the wear process. The contribution of the interaction between the hard wear-resistant phase and the tough phase in WCI to the wear resistance decreased with increasing hardness of the pearlite matrix.
