Catalytic Growth of High-Performance Graphite-like Carbon Films on a Nitrided Substrate: Experimental Study and First-Principles Calculations

“…The results of fitted surface roughness show that the 5203:1 sample exhibits the highest roughness ( S a ) of 310.0 nm, whereas the 5201:3 sample exhibits the lowest roughness ( S a ) of only 80.7 nm. Because of the shadow effect, the surface roughness and morphology of GLC films inherit and replicate the roughness and morphology of the surfaces of the nitrided substrate. ,, During the nitriding process, nitride particles (Fe 3 N phase; Figure a) grow on the surfaces of nitrided layers under high nitrogen potentials at high temperatures, increasing the surface roughness of GLC films. ,, Therefore, the roughness of the samples is positively correlated with the relative content of the Fe 3 N phase (Figure b). For example, the 5203:1 sample exhibits the highest roughness because the highest amount of nitrides (Fe 3 N phase) is formed in this sample under high nitrogen potentials at high nitriding temperatures.…”

“…21,25,40 During the nitriding process, nitride particles (Fe 3 N phase; Figure 1a) grow on the surfaces of nitrided layers under high nitrogen potentials at high temperatures, increasing the surface roughness of GLC films. 6,7,10 Therefore, the roughness of the samples is positively correlated with the relative content of the Fe 3 N phase (Figure 1b). For example, the 520�3:1 sample exhibits the highest roughness because the highest amount of nitrides (Fe 3 N phase) is formed in this sample under high nitrogen potentials at high nitriding temperatures.…”

“…The tribological process results in extra energy consumption and progressive loss of materials, which deteriorate performance and decrease the reliability of the system. Numerous attempts have been made to minimize or control wear and friction in mechanical systems, particularly for steel, which is commonly used to fabricate moving parts in many mechanical systems. − In the past few decades, conventional thermo-chemical treatments such as carburizing , and nitriding , have been used to reduce wear damage. However, previous studies have reported that the improvement in the coefficient of friction (COF) is not impressive compared to the improvement in wear resistance. − …”

Influence of Quenching and Tempering on the Tribological and Corrosion Behavior of Plasma‐Nitrided Society of Automotive Engineers 52100

“…[4] In addition, corrosive environments can aggravate the deterioration of these elements. [5,6] The failure of these elements causes significant losses in the production process due to the stoppage of the machine store, placing the damaged bearing and adjacent elements. [7,8] Therefore, it is necessary to use surface technology to improve the mechanical properties and tribological behavior of SAE 52100 steel.…”

Effect of Rapid Hollow Cathode Plasma Nitriding Treatment on Corrosion Resistance and Friction Performance of AISI 304 Stainless Steel

“…However, the mechanical and frictional characteristics of austenitic stainless steel present inherent limitations that may result in friction-induced damage to the workpiece, particularly in corrosive environments [4][5][6]. Plasma nitriding has the advantages of high efficiency, low cost, and less pollution [7][8][9][10][11]. It is a standard surface-strengthening treatment method for austenitic stainless steel [12][13][14][15][16].…”
