“…The increase in temperature to 860 ∘ C and pressure up to 50 MPa ( Figure 3) enabled achieving high densification level (> 98 %). The combined impact-abrasive wear tribo-device [11] was applied to test samples, with impact energy of 5.6 J and frequency of impacts being 27.5 Hz provided by impact generator (industrial hammer drill from Makita). The sample was experiencing reciprocative movement and was pressed (by the dead-weight system) against the rotating wheel (made from WC-Co) with a force of 49 N; linear abrasion velocity was 1 m/s.…”

“…The second simulated sample having a 2×2×2 mm lattice scaffold is illustrated in Figure 12. During normal operation of the tribo-device ( Figure 10(c)) [11] both rotation of the wheel (abrasive action) and impact between the sample and the wheel are provided but for current simulation, it was important to demonstrate the extreme case with impacting only (Figure 10(a)). The position of impacting was also changed.…”

An approach of sintering 3D metal printed lattices and diamond nickel-coated particles is proposed which can be used for the production of tunnel boring machine (TBM) cutters and mining equipment blades. Nickel-coated diamond particles are mixed with titanium powder and incorporated into a lightweight Ti6Al4V (3D printed) lattice with the help of spark plasma sintering (SPS) method. Effect of Ti6Al4V lattices size, diamond particles size, and nickel coating layer thickness on wear resistance of composites is discussed. Functionally graded lattice (FGL) structures were produced by selective laser melting (SLM) method, representing an increasingly growing additive manufacturing engineering area introduced in material engineering. Impact-abrasive tribo-device (IATD), scanning electron microscopy (SEM), X-ray diffraction (XRD), energy-dispersive spectroscopy (EDS), and optical surface profiler (OSP) were used to characterize samples. An ab initio design of diamond-metal composite is based on the improvement of impact and abrasive wear resistance of Ti6Al4V by adding diamond particles and by applying of gradient lattice structure. The specimen with larger size of the diamond particle and thicker Ni coating has better wear resistance. In addition, ANSYS software simulations were done to analyze the effect of the presence of 3D printed lattice via nonlinear finite element AUTODYN solver under impact test. Diamond-based gradient composite material produced by combined SLM-SPS methods can be applied in applications where resistance against impact-abrasive wear is important.

“…Impact abrasive wear, as one of the forms of abrasive wear, prominently increases the mass loss of materials as it combines friction and impact [6], has been gradually reported in recent years. Latest researches, however, start focus on advanced wear service materials such as metal matrix composites, coating, and cemented carbide [7][8][9]. But it is well-known that iron and steel material cannot be replaced in engineering, such as high chromium white iron (HCWI), has widely used in several structural applications as the third-generation wear-resistant materials, which attributed to the multiple advantages of HCWI such as high strength and wear resistance [10].…”

Effect of impact energy on wear behavior of high chromium white iron produced by liquid die forging

et al. 2018

View full text Add to dashboard Cite

Impact abrasive wear behavior of high chromium white iron (HCWI) produced by liquid die forging process were investigated. the wear tests were performed with the MLD-10 abrasive wear testing machine, using SiO2 abrasive and with four impact energies of 1.5 J, 2.5 J, 3.5 J and 4.5 J for 120 min. The results indicated that the cumulative volume loss of HCWI sample increases with the growth of impact energy, and exhibits best wear resistance under low impact condition. For given impact energy, the volume loss increases with the increasing of wear time, which shown an approximately liner tendency. The macro-morphologies, SEM images of worn surface and cross-sectional images of wear samples were observed by optical microscope and SEM, and the wear mechanism and characteristics were analyzed. Results shown that the wear characteristics is mainly based on the shallow ploughing and accompanied by plastic deformation under lower impact energy, while the fatigue peeling and embedded abrasive become the most significant characteristics when the impact energy is higher.
