Flow based Erosion e corrosion problems are very common in fluid handling equipments such as propellers, impellers, pumps in warships, submarine. Though there are many coating materials available to combat erosionecorrosion damage in the above components, iron based amorphous coatings are considered to be more effective to combat erosionecorrosion problems. High velocity oxy-fuel(HVOF)spray process is considered to be a better process to coat the iron based amorphous powders. In this investigation, iron based amorphous metallic coating was developed on 316 stainless steel substrate using HVOF spray technique. Empirical relationships were developed to predict the porosity and micro hardness of iron based amorphous coating incorporating HVOF spray parameters such as oxygen flow rate, fuel flow rate, powder feed rate, carrier gas flow rate, and spray distance. Response surface methodology(RSM) was used to identify the optimal HVOF spray parameters to attain coating with minimum porosity and maximum hardness.

This article analyzes the transmission line characteristics of plasmonic hybrid metal insulator metal(HMIM) wave-guide, circular ring resonator(CRR) based dual-band band-pass filters with two transmission poles in both pass-bands in the optical regime using coupled line feed. The transmission line characteristics of an HMIM waveguide, such as characteristic impedance(Z_(PV)), effective refractive index(n_(eff)) and propagation length(L_(spp)), have been obtained by using full wave simulation.

Laparoscopic, Endoscopic and Robotic Surgery 2024年第1期7卷 44-47页

Laparoscopy within the urology field has undergone a noteworthy surge in popularity over the past decade,with particular importance given to renal surgeries such as simple nephrectomy,radical nephrectomy,donor nephrectomy,nephroureterectomy,and partial nephrectomy.1 This shift toward laparoscopic procedures among urologists can be attributed to the many benefits of these procedures,including reduced postoperative pain,shorter hospital stays,and faster recovery times.2 However,as with any evolving surgical technique,laparoscopic procedures in renal surgery bring forth their own set of distinctive challenges and complications.
