On the surface of zirconium alloy, TiN coatings with and without Cr interlayer were prepared in N2/Ar mixed gas atmosphere by physical vapor deposition technology. The morphology, micro-composition particles, roughness, phase constituent high-temperature oxidation resistance characterized scanning electron microscope (SEM), energy dispersive spectrometer (EDS), roughness measuring instrument, x-ray diffractometer (XRD) chamber electric furnace, respectively. results show that, comparison...
Abstract The deformation and surface settlement need more attentions when a foundation pit is adjacent to old buildings. of Liangyuan Garden museum project was used as the background, author analyzed monitoring data which gathered from beginning end. results show that lateral mainly occurs in excavation stage, influence surrounding buildings on needs be considered. retaining structure with inner support system shows good coordination ability obvious spatial characteristics. Entering...
Commercial 5052 aluminium alloy sheets were subjected to a severe plastic deformation technique known as constrained groove pressing (CGP) at room temperature. The impact of repeated CGP, upon the microstructure refinement was investigated by polarised optical microscope well transmission electron microscope. Changes in mechanical properties, measured tensile test and hardness test, related evolution microstructures. Moreover, microhardness, on polished cross-section each as-pressed sheet,...
Three groups of commercial 1050 Al alloy were subjected to equal channel angular pressing (ECAP) at room temperature using route A, C and Bc, respectively. Mechanical properties fracture modes as-annealed ECAPed samples investigated. The microhardness fabricated by ECAP increases a factor about 1.5 compared the state. ultimate tensile strength (UTS) significantly after ECAP, while elongation decreases. But they are strongly dependence on number passes route. UTS processed Bc best,...
Objective To investigate the relationship between nanohardness and mierostructure of dentin enamel human teeth. Methods Nano indentation was used to determine dentin; TEM IR were utilized observe microstrueture crystalline characteristic. Results The mean [( 4. 92 ± 0. 40 ) Gpa]was significantly higher than that [(1.17 14) Gpa]. A large quantity hydroxyapatite (HA) crystals uniform lattice stripe found in hut not dentin. Conclusions difference is related their density, inorganic morphology...

Abstract Tailing acidification is a common objective phenomenon in sulfide mine tailings. In mines, the tailings sand particles are fine. With accumulation of time, minerals contained will be oxidized to generate sulfate and sulfuric acid under catalysis oxidizing bacteria, water, oxygen oxidant (such as Fe 3+ ), acidic waste liquid further undergo double decomposition reaction with metal oxides insoluble precipitates, which weaken shear strength It affects stability The author studies ore...
Sulfide minerals (mainly FeS2) contained in lead-zinc tailings are easy to be acidified the air. The acidification mechanism is that tailing sand generates sulfuric acid and sulfate under catalysis of oxidant, water oxygen. acidic liquid generated by reaction will continue react with metal oxides form an insoluble precipitate.In order reveal corresponding changes chemical properties physical during acidification, a series processes natural conditions were simulated immersion test...
