Chill sensitiveness and thermal analysis parameters relationship in hypo-eutectic, Ca and Ca-La inoculated commercial grey cast irons by Stefan E., Chisamera M., Riposan I.

“…Representative temperatures on the cooling curves and under-cooling degrees referring to the meta-stable eutectic temperatures were determined and correlated with the chill [carbides/graphite formation sensitiveness], in different solidification conditions [cooling modulus, wedge shape castings, resin sand mould]. Supplementary addition of La to Cabearing inoculants had limited, but specific benefits in these cast irons: lower eutectic recalescence and maximum recalescence rate, higher GRF1 and lower GRF2 graphitizing factors, and lower value of the first derivative at the end of solidification. …”

Research on the Preparation of Modified TiO₂ Composite Coatings with Anti-Fouling and Flashover Resistance by ZHANG Jie, ZOU Junwen, LIU Xueguang, LI Xiaoying

“…In order to effectively reduce the occurrence of pollution flashover accidents caused by surface contamination of transmission line insulators， a new fluorocarbon coating material was prepared by combining modified nano-TiO2， PTFE and fluorocarbon resin FEVE using compressed air spraying technology.The optimum addition amount of modified TiO2 particles was discussed.The microstructure was studied using scanning electron microscopy (SEM) and atomic force microscopy (AFM).The hydrophobicity， self-cleaning properties and anti-ultraviolet aging resistance were analyzed using a contact angle measurement instrument.The results showed that the optimum addition amount of modified nano-TiO2 was 4%，the adhesion of the coating reached grade 0，and the maximum static contact angle was 121°.The surface of the anti-pollution flashover composite coating prepared with modified TiO2 exhibited numerous micro-nano scale columnar cone tip structures， resulting in higher roughness.Its hydrophobicity， self-cleaning ability， and anti-ultraviolet aging resistance were improved， demonstrating excellent antipollution flashover performance.…”
