    Tribocorrosion Behavior of Laser-Cladded FeCrBSi Medium-Entropy Alloy Coatings by WANG Yanfang, ZHANG Yunpeng, CAO Chenjie, LIU Yanle, WANG Yunxuan, SHI Zhiqiang

    Published 2025-05-01
    “…Marine oil and gas engineering equipment suffers significant damage due to seawater corrosion and mechanical wear.Medium-entropy alloys, with their combined wear and corrosion resistance, are considered ideal materials for surface protective coatings.In this study, a FeCrBSi medium-entropy alloy coating was prepared on the surface of 316L stainless steel via laser cladding technology.The microstructure and tribocorrosion coupling behavior of the cladded layer were analyzed using X-ray diffraction (XRD), metallographic microscopy and electrochemical corrosion and tribological tester.Results showed that the cladding layer consisted of dual-phase FCC and BCC solid solutions.The cladded zone was primarily composed of dendritic structures, while the bonding zone exhibited planar crystals.The average hardness of the FeCrBSi medium-entropy alloy coating reached 939 HV0.2, approximately 4.4 times that of the 316L stainless steel substrate.As the applied frictional load increased, the coefficient of friction of the coating decreased, with average values ranging from 0.2 to 0.5.The maximum wear volume was 0.052 mm3, indicating a significant improvement in wear resistance compared to the substrate.Electrochemical testing in a 3.5%(mass fraction) NaCl solution demonstrated superior corrosion resistance compared to 316L stainless steel, as indicated by a self-corrosion potential of -0.05 V and a corrosion current density of 1.45×10-7 A/cm2.Under the combined effect of frictional load and externally applied corrosion potential, both the average current density and wear volume increased with increasing potential, while the friction coefficient decreased.A synergistic interaction between corrosion and wear was observed.Notably, corrosion-induced wear contributed over 92.5%to the total material loss, demonstrating its dominant role.…”

    Relationship between obstructive sleep apnea hypopnea syndrome and the occurrence and progression of type 2 diabetic nephropathy by 钱科威, 顾晓琦, 曹蓓, 袁婕, 孙晓红, 章敏

    Published 2021-01-01
    “…Objective To explore the correlation between obstructive sleep apnea hypopnea syndrome(OSAHS)and diabetic nephropathy(DN)in type 2 diabetes mellitus(T2DM)patients.Methods A total of 92 T2DM patients with DN during June 1-May 30,2020 were selected while 75 T2DM patients without DN during the same period designated as controls.All patients were tested for serum cystatin C,γ-aminobutyric acid(γ-GABA)and urine albumin excretion(UAE)on the basis of routine diagnosis and treatment.Polysomnograph was utilized for 8-hour continuous recording and apnea-hypopnea index(AHI),minimum night blood oxygen saturation(LSaO<sub>2</sub>)and night average blood oxygen saturation(MSaO<sub>2</sub>)were recorded.Results No inter-group statistical differences existed in age, gender composition, body mass index(BMI),fasting blood glucose, hypertension or hypercholesterolemia.The average diabetic duration was prolonged in DN patients, the incidence of OSAHS spiked.The levels of HbA1 c, CysC and AHI rose while the levels of LSaO<sub>2</sub>,MSaO<sub>2</sub> and γ-GABA declined(all P<0.05).They were divided into three groups of normal albuminuria, micro-albuminuria and massive albuminuria according to the level of UAE.The disease courses of DN and AHI became elongated markedly while LSaO<sub>2</sub>,MSaO<sub>2</sub> and γ-GABA declined markedly(all P<0.05).Further multivariate Logistic regression analysis indicated that AHI was an independent risk factor for an onset of DN(P=0.044)while LSaO<sub>2</sub>,MSaO<sub>2</sub> and γ-GABA were independent protective factors for DN in T2DM patients(all P<0.01).Conclusion OSAHS is correlated with DN occurrence so that alleviating OSAHS may delay the progression of DN.…”
