“…In the related literature, surface alloying is usually done by advanced techniques such as laser cladding due to significant advantages like fast processing speed, relative cleanliness, a very high heating/cooling rate (105 K/s) and high solidification velocity (up to a maximum of 30 m/s) [13]. However, there are practically simpler and more cost-effective methods like gas tungsten arc welding in which by discreet controlling of welding parameters, enhanced surface and wear properties can be achieved [14].…”

“…The size of Cr-SiC particles is about 100 lm, close to the initial size. The particle morphology is better than what was reported in previous studies (Ref [7][8][9]. Cr-SiC particles were injected into the tail of molten pool and then reacted with the matrix.…”

In this study, SiC particles were first coated with Cr to form a layer that can protect the SiC particles from dissolution in the molten pool. Then, the Cr-SiC powder was injected into the tail of molten pool during plasma-transferred arc welding process (PTAW), where the temperature was relatively low, to prepare CrSiC particles reinforced Fe-based alloy coating. The microstructure and phase composition of the powder and surface coatings were analyzed, and the element distribution and hardness at the interfacial region were also evaluated. The protective layer consists of Cr 3 Si, Cr 7 C 3 , and Cr 23 C 6 , which play an important role in the microstructure and mechanical properties. The protective layer is dissolved in the molten pool forming a flocculent region and a transition region between the SiC particles and the matrix. The tribological performance of the coating was also assessed using a ring-block sliding wear tester with GGr15 grinding ring under 490 and 980 N load. Cr-SiC particles-reinforced coating has a lower wear rate than the unreinforced coating.

“…316L stainless steel (abbreviated by 316L) has increasingly wide utilization in automobile, aerospace, marine, and medical treatment field owing to its outstanding properties of corrosion resistance, ductility, and biocompatibility. However, it is not efficient enough when the strength and wear resistance are both needed [1][2][3]. e performance of this material can be improved via incorporating hard, brittle ceramic reinforcements into the steel matrix, namely, producing particulate reinforced metal matrix composites (MMCs).…”

“…e performance of this material can be improved via incorporating hard, brittle ceramic reinforcements into the steel matrix, namely, producing particulate reinforced metal matrix composites (MMCs). Compared with various hard ceramic particles [2][3][4][5][6][7][8][9], titanium carbide (TiC) powder is more suitable and has been widely used as reinforcement in the steel matrix because of its high hardness and strength, high melting point, low density, large elastic modulus, and relative stability [9]. e uniform dispersion of TiC powder within the 316L matrix can result in superior performance of 316L in the application requiring high strength and wear strength.…”

This paper presents a numerical investigation on the 2D uniaxial die compaction of TiC-316L stainless steel (abbreviated by 316L) composite powders by the multiparticle finite element method (MPFEM). The effects of TiC-316L particle size ratios, TiC contents, and initial packing structures on the compaction process are systematically characterized and analyzed from macroscale and particulate scale. Numerical results show that different initial packing structures have significant impacts on the densification process of TiC-316L composite powders; a denser initial packing structure with the same composition can improve the compaction densification of TiC-316L composite powders. Smaller size ratio of 316L and TiC particles (R316L/RTiC = 1) will help achieve the green compact with higher relative density as the TiC content and compaction pressure are fixed. Meanwhile, increasing TiC content reduces the relative density of the green compact. In the dynamic compaction process, the void filling is mainly completed by particle rearrangement and plastic deformation of 316L particles. Furthermore, the contacted TiC particles will form the force chains impeding the densification process and cause the serious stress concentration within them. Increasing TiC content and R316L/RTiC can create larger stresses in the compact. The results provide valuable information for the formation of high-quality TiC-316L compacts in PM process.
