Engineering nanocontainers with encapsulated inhibitors onto graphene has been an emerging technology for developing self-healing anticorrosion coatings. However, the loading contents of are commonly limited by inhomogeneous nanostructures platforms. Here, we propose activation-induced ultrathin platform (UG-BP) homogeneous growth polydopamine (PDA) benzotriazole (BTA). Ultrathin prepared catalytic exfoliation and etching activation provides ideal ultrahigh specific surface area (1646.8...
Due to their high corrosion resistance, non-transformation, and non-magnetism, austenitic stainless steels can meet the service requirements. However, low hardness poor wear resistance impose serious drawbacks. A combination of plasma nitriding coating as a surface treatment has been shown improve without affecting performance. In this work, rapid conducted on AISI 316L using hollow cathode discharge assisted apparatus. The CrN/CrTiAlSiN/WCrTiAlN multilayers consisted CrN bottom-layer,...
Green-synthesized gel materials can efficiently absorb and remove organic dyes from wastewater. This investigation designed synthesized a novel modification method of sodium alginate beads based on the protein glycosylation reaction (Maillard reaction) using green chemistry principles. The prepared were subsequently applied to examine their efficacy in adsorbing dye methylene blue. adsorption process mechanism characterized analyzed. At an equilibrium 300 K, value reach 908 mg/g. dry casein...
Functionalized multi‐walled carbon nanotubes (FMWCNTs) have been incorporated into binary composites of poly(amide‐imide) (PAI) and polyaniline (PANI) to improve their conductive mechanical performances. The conductivity PAI/PANI/FMWCNTs ternary significantly increased from 10 −3 8.3 S m −1 with increasing the weight ratio FMWCNTs 0 wt%, which is much higher than that sum PAI/PANI PAI/FMWCNTs composites. enhanced mainly ascribed be more intensive percolating network formed in due hydrogen...
Ti6Al4V titanium alloys, with high specific strength and good biological compatibility the human body, are ideal materials for medical surgical implants. However, alloys prone to corrosion in environment, which affects service life of implants harms health. In this work, hollow cathode plasm source nitriding (HCPSN) was used generate nitrided layers on surfaces improve their resistance. were NH3 at 510 °C 0, 1, 2, 4 h. The microstructure phase composition Ti-N layer characterized by...
AISI 4140 low alloy steel samples were treated using conventional plasma nitriding (CPN) and hollow cathodic source (HCPSN) treatments. The results show the substantial impact of electric potential process on microstructure, topography, surface roughness chemical characteristics CPN HCPSN nitrided samples. sample presented ε-Fe2–3N phase at a higher intensity than sample. XPS showed that modified consisted nitrides oxides during deposition. Electrochemical impedance spectroscopy...
High-voltage electric pulse (HVEP) technology has been gradually adopted as an effective method in the drainage and utilization of coalbed methane (CBM) low-permeability coal reservoirs. An experimental device was established to study structural variation characteristics bituminous samples treated by HVEP. The structure parameters before after HVEP treatment were measured using a scanning electron microscope low-temperature nitrogen adsorption. Additionally, current waveforms process...
The increasingly strict emissions regulations put forward higher request of NOx control to diesel engines. Water addition is considered be an effective way reduce emissions. However, most studies around the world concerned mainly about effect water on reduction. engine efficiency was not paid as much attention A series experiments were carried out test bench based a two cylinder with modifications adding common rail system and direct injection system. effects combustion indicated thermal...
Abstract The formation and diffusion of plasma are complex critical processes in nitriding. A stable high-concentration atmosphere can effectively increase the rate thickness layer. In this study, a two-dimensional multi-physics model integrating physical kinetics, energy transfer, mass electromagnetic induction was developed. effect hollow-cathode structure on distribution investigated, edge observed nitrided metals eliminated. impacts essential parameters were simulated using developed...
Abstract Two conductive carbon materials, one with a beaded-like structure (carbon black, ECP) and another tube-like (functionalized multi-walled nanotubes, FMWCNTs), were added into poly(amide-imide) (PAI) matrix. Combining the advantages of ECP (good compatibility) FMWCNT (high conductivity), conductivity was improved from 3.7 S m −1 for PAI/FMWCNT polymer composites to 100 PAI/FMWCNT/ECP ternary composites, much higher than that sum PAI/ECP PAI/FMWCNT. The tensile strength increased 40 70...
The present study aimed to predict the envelope surfaces from facial morphology. Condylar for 34 healthy adults were formed and simplified as sagittal section curves.
