Recently, more and conductive nanocomposites are used to enhance the sensing characteristic of flexible sensors. However, influence composite structure on performance sensor is rarely investigated. Herein, two structures carbon black (CB)/graphene nanosheets (GNs) for three-dimensional piezoresistive Based CB GNs, three sensors with GNs fabricated. Experimental results show that different result in several times differences sensitivity gauge factor. Among samples, (first coating then filling...
Recently, the manufacture of high‐entropy‐alloy (HEA) parts by selective laser melting (SLM) has been extensively studied. However, problems high tensile residual stress, undesirable microstructure, and unstable mechanical properties in HEA caused SLM process are difficult to be solved simultaneously. Herein, a warm shock peening (WLSP) is used obtain strength, stable property, favorable stress SLMed FeNiCrCo regulating microstructure material. Experimental simulation results show that WLSP...
Heat-assisted magnetic recording (HAMR) technology is a great way to achieve higher storage density. In HAMR, dynamic performance of the head-disk interface (HDI) critically important for read/write stability. Lubricant bridge formation and lubricant transfer can significantly deteriorate HDI performance. this paper, 3-D full-atom model slider-lubricant-disk substrate system established study in HAMR. The overlayers slider disk are made diamondlike carbon, main lubricating ingredient...
This work studies the dynamic behavior of diamond-like-carbon (DLC) impurity in head-disk interface (HDI) HAMR using molecular dynamics method. It is found that during heating process, a perfluoropolyether (PFPE) lubricant bridge between slider and disk formed. The floats when temperature rises, it can adhere to bottom with PFPE molecules. DLC doesn't fall back onto layer adhered substrate, even drops.
High-entropy alloys (HEA) have attracted much attention due to their excellent mechanical properties. Laser shock peening has been an effective way improve the strength and fatigue performance of metals. However, further improvement strength, beneficial residual stress, stability a challenge. In this work, warm laser (WLSP) HEA after selective melting is investigated systematically understand mechanisms during high strain rate deformation strengthening mechanism for enhanced stabilized A...
