“…The mechanical properties of piston ring materials can be augmented through surface modification technology, which significantly reduces friction at the PRCL interface [10]. Techniques such as coating piston rings with zirconia ceramics using plasma spray can reduce wear [11]. Laser treatment, when combined with the appropriate ceramic grains for surface treatment, effectively enhances the friction and wear resistance of piston rings [12].…”

Internal combustion engines, during their operation, subject the piston to high-temperature and high-pressure conditions, requiring it to endure intense, continuous reciprocating motion. This strenuous process leads to significant wear and tear. Among the engine’s crucial components, the piston ring plays a pivotal role but is particularly susceptible to wear. Therefore, extensive research has been devoted to investigating the wear of piston rings, a critical sealing component within internal combustion engines. To address the high cost of existing coating methods, which hinders widespread application, we propose a bionic design approach inspired by groove structures observed on earthworm bodies, aimed at enhancing the wear resistance of piston rings. Bionic piston rings featuring optimally designed groove structures inspired by the earthworm’s anatomy were designed. These rings exhibited varying groove depths (1 mm, 2 mm, and 3 mm), groove widths (0.1 mm, 0.3 mm, and 0.5 mm), and groove spacings (0.1 mm, 0.2 mm, and 0.3 mm). We conducted thermal–structural coupling analyses on both standard piston rings and these bionic counterparts. The results revealed that the maximum stress was concentrated at the first piston ring, precisely at the opposing region of the end gap. Thus, the initial piston ring endured the primary frictional losses. Moreover, a comparison of stress levels between bionic rings and the standard ring revealed that the bionic groove structure substantially reduced stress and minimized stress concentration, thus enhancing wear resistance. Groove width had the most notable influence on wear performance, followed by groove depth and groove spacing. Optimal wear resistance was achieved when the groove depth was 3 mm, groove width was 0.1 mm, and groove spacing was 0.1 mm. Subsequently, we constructed a piston ring friction test bench to validate the wear resistance of the most effective piston ring. The results indicated that the wear resistance of the bionic piston ring exceeded that of the standard piston ring by up to 19.627%. Therefore, incorporating a bionic groove structure within the piston ring can effectively reduce surface friction and enhance wear resistance. This, in turn, can enhance the operational lifespan of internal combustion engines under favorable working conditions.

“…In this paper, I observed that the coating surface of the piston ring protects the piston ring against thermal and mechanical effects during friction. Plasma spray technology is used in this research, and salt spray testing is a standardized method used to test the corrosion resistance of coated specimens and to investigate the tribological properties under dry friction conditions for aluminium plasma-sprayed nanostructured zirconia coatings compared to traditional zirconia coatings [4]. Various mechanical analyses were conducted and the wear effect with different percentages of alumina reinforcement was studied and used for the stir casting technique, a conventional metal-forming technology [5].…”

This paper is respecting the evaluation of stress distribution on IC engine (four-stroke) piston ring and analysis of finite element by using FEA software. The purpose of this analysis is to calculate strain for SiC reinforced ZrB2, A360, A2618 and deformation resulting through ring elastic pressure and gas pressure. The total deformation and strain on the piston ring have been obtained in this project. The characteristics of such vibrations are analyzed with the help of solid works software and analysis of finite element is performed on the Ansys workbench software. The material used is Silicon Carbide reinforced Zirconium Diboride (SiC reinforced ZrB2), Aluminium alloy (A360), Aluminium alloy (A2618). This is a ceramic matrix composite (CMC) which has good safety factor and lower cost. The experiment is conducted on three types of composites to evaluate the strain on SiC reinforced ZrB2, A360, A2618 resulting from the total deformation and strain. Compressive strength has also been analyzed for the structural model of the piston ring.
