“…This was supported by a study which reported a significant increase in wear resistance which was observed on the piston surface by using SiC for surface modification [10]. Using gray cast iron as matrix and WC as reinforcement, mass loss was found to be 30.25 mg/cm 2 in the unreinforced sample, and 8.33 mg/cm 2 in the reinforced sample that also supports the effect of reinforcement on wear resistance [11].…”

“…Table 1 is the chemical composition of gray cast iron. Then the four sets of cylinder liners were divided into two parts, one for the cutting force test and the other for microstructure observation and mechanical property test [4]. The cutting force measurement experiment equipment is the CA6140 lathe which has been transformed by numerical control.…”

Abstract. Cutting performance of gray cast iron cylinder has been valued in the recently years. The microstructures and mechanical properties of four sets of gray cast iron cylinder liners were compared and studied. At the same time, the effect of microstructure on the cutting performance was explored. It is concluded that uniform matrix of gray cast iron will improve the cutting performance, and the higher the graphite content, the finer the size, the better the cutting performance. Ultimately, the condition of gray cast iron with good mechanical properties and cutting performance is below: fine, curved, disordered and evenly distributed flaky graphite structure and large lamellar spacing and uniform pearlite matrix.

“…[4] The first way involves placing one reactant of a selected type of carbide in the form of a vanadium plate [5] or tungsten wire [6] into the mold cavity, while the second reactant is introduced as a component liquid alloy poured into the mold cavity. The molten alloy activates the reaction between the reactants introduced into the mold, and reinforcement particles such as vanadium carbide (VC) [5] and tungsten carbide (WC) [6,7] are formed directly in the casting. Zhong et al [8] reported a method of producing WC reinforcement on the surface of an iron matrix based on a W plate introduced into a mold cavity, which is then filled by a liquid alloy.…”

“…The essence of the second method is the placement of green compacts containing mixtures of TiC or TiC and TiB 2 reactants undergoing the SHS reaction [9][10][11][12][13][14][15][16][17][18][19][20][21] in a mold cavity. [5][6][7][8][9][10][11][12][13][14][15] Similar to the previous method, the liquid alloy poured into the mold cavity activates the SHS reactions, but due to the self-sustaining reaction occurring in the whole compact, it is possible to fabricate an LR in a wide range of dimensions. This means that this method is particularly attractive for the local reinforcement of castings.…”

The dependences of the macro-and microstructures as well as the hardness of local TiC-Fe-type reinforcements (LR) fabricated in situ in steel casting using compacts containing different contents of TiC reactants and the addition of an Fe moderator have been investigated using scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and Vickers hardness (HV) tests. Five powder mixtures were selected for compact preparation; one of them contains only TiC reactants, while the other four contain TiC reactants as well as 10, 30, 50, and 70 wt pct Fe moderator additions, respectively. Next, the ready compacts were introduced to the mold cavity and poured by cast steel for the in situ LR fabrication. This is the first time, through this study, that the fragmentation phenomena was revealed by macrostructural observations of the LR produced with only the TiC reactants. The increasing Fe content gradually limited the fragmentation and infiltration processes and stabilized the dimensions of the LR. With the increasing contents of the Fe moderator, the refinement of the TiC particles in the LR was observed. Due to the limited infiltration process and high surface content of the TiC, the LR produced with 30 wt pct Fe exhibited the greatest hardness.
