Enter your email address to subscribe to this blog and receive notifications of new posts by email. In addition, NANOMYTE coatings are versatile and can be modified to introduce color and other features to meet performance and aesthetic requirements. Request a Quote . Avoid contact with eyes, skin, and clothing. Sci. Self NEI has developed a line of self-healing top coats, where a physical self-healing phenomenon leads to gap closing and crack sealing. HHS Vulnerability Disclosure, Help Acta Biomater. For example, self-healing epoxies can be incorporated into metals in order to prevent corrosion. Polymer coating has extrinsic healing properties. Ab initio calculations carried out at the MP2/6-311++G(d,p) level of theory complement the experimental studies. Alternatively, NEI offers custom coating services for a nominal fee and would be happy to coat your sample substrates for evaluation purposes. NANOMYTE TC5001 is part of NEIs expanding portfolio of anti-corrosion coating systems, including pretreatments and topcoats that protect steel, aluminum and magnesium from corrosion. The effects of sintering temperature A, axial pressure B, and holding time C on density, hardness, and strength are studied by range analysis, analysis of variance, and multi-index matrix analysis. You can download the paper by clicking the button above. Despite the high amount of BCC, which is referred to as the brittle phase, newly developed EHEAs exhibited superior fracture toughness.
