Diamond is widely acknowledged as the hardest naturally occurring material. Nevertheless, when exposed to friction against ferrous metals, it prone graphitization or amorphization, which limits utilization of its extremely high hardness and wear resistance. These issues have persisted for decades without an effective solution. Here, we report that a covalently bonded heterostructure with mixed-dimensional carbons high-performance solid lubricant could effectively reduce diamond surface...
Carbon fiber-reinforced silicon carbide matrix (Cf/SiC) composites have been widely used in aerospace for its superior properties. However, due to high hardness, heterogeneity, and anisotropy, many problems such as machining damage, low process efficiency, rapid tool wear are encountered Cf/SiC composite. In this study, laser-induced oxidation-assisted milling (LOAM), novel hybrid process, was proposed enhance machinability of composites. Pulsed laser induce reaction between oxygen. Easily...
Diamond tools experience severe chemical wear when machining ferrous metals, which hinders their practical applications. In order to improve the resistance of diamond cutting tools, in diamond-graphite strong covalent structure prepared by laser induced solid-phase diffusion, carbon nanosheets (CNS) can be obtained electrochemical stripping graphite layer onto matrix, provides a new way limitations application. After 14400 cycles reciprocating sliding against GCr15 ball at normal load 2–8 N,...
Polymer gels can be effectively applied to plug fractured reservoirs and carbonate cave strata. Herein, polyvinyl alcohol (PVA), acrylamide, 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) were used as raw materials prepare interpenetrating three-dimensional network polymer using formation saltwater in the Tahe oilfield (Tarim Basin, NW China) a solvent. The effect of AMPS concentration on gelation properties PVA high-temperature was analyzed. Further, strength viscoelastic gel studied....
The shipping industry is vital to global trade. Unfortunately, this negatively impacted on a large scale by biofouling, process whereby unwanted organisms accumulate submerged surfaces, massively affecting traveling speed and fuel consumption. Fortunately, antifouling coatings have been developed combat problem. This review summarizes the of biofouling briefly discusses history coating development. Moreover, eight major are reviewed, including bionic microstructure, self-polishing, fouling...
This paper first develops a cryogenic cutting system with adjustable jet temperature (− 196~20 °C), and then carries out series of dry turning experiments for titanium alloy. Metallographic microscope is used to observe the chip morphology alloy geometric characteristic parameters are measured using Digimizer image measurement software. The influence speed cooling conditions on morphology, height ratio, serrated pitch has been analyzed. experimental results reveal that play significant roles...
Owing to reliability and high strength-to-weight ratio, large thin-walled components are widely used in the aviation aerospace industry. Due complex features sequence involved machining process of components, deformation component is easy exceed specification. In order address problem, it important retain appropriate finishing allowance. To find overall deformation, allowance-induced (web allowance, sidewall allowance) initial residual stress-induced were considered as major factors....
Boundary conditions significantly influence the near-field dynamics of bubbles. This study employs numerical simulations to investigate coupling characteristics high-pressure bubbles near solid boundaries and moving spherical boundaries. It focuses on effects sinking velocity sphere initial bubble–boundary distance bubble evolution loading characteristics. The results indicate that an increase in sphere's or a decrease leads tearing during collapse process. generates high-speed water jets...
