spectroscopy (AES). A high adhesion of up to 80 N was demonstrated by scratching tests for the multi-layered coatings. Nanoindentation tests were performed to determine the hardness and elastic modulus......
, elastic modulus, and scratch resistance of a glass-ceramic rigid substrate were measured by nanoindentation and nanoscratch, and the fracture toughness was measured by indentation using a Vickers indenter......
at the fluence ranging from 1×1014 to 8×1015 ions/cm2 has been investigated by conventional transmission electron microscope, X-ray diffraction line profile analysis (XRDLPA) and nanoindentation. XRDLPA shows......
and mechanical properties were investigated by XRD, SEM and Nanoindentation. It turns out that hardness of samples increases with decreasing modulation wavelength (Λ) and then dropped at small Λ......
by nanoindentation testing. The results showed that the hardness increased drastically with decreasing hAldown to about 20 nm, whereafter the hardness reached a plateau that approaches the hardness......
were investigated by nanoindentation tests, X-ray residual stress analysis and scanning electron microscope observation in four-point bending tests. The results show that the plastic properties......
(AlCrMoNbZr)1-x-yNyOx高熵合金涂层的制备及性能研究常鸿1,赵莎2,刘春海21. 核工业西南物理研究院2. 成都理工大学材料与化学化工学院摘 要:采用多靶磁控共溅射技术的单靶功率可调特点,在Zr-4合金基底上,通过调节O2流量制备出(AlCrMoNbZr)1-x-yNyOx高熵合金涂层.利用X射线衍射仪(XRD),扫描电子显微镜(SEM),原子力显微镜(AFM),纳米压痕仪(nanoindentation)以及电化学工作站等对不同O2流量下制备的(AlCrMoNbZr)1-x-yNyOx高熵合金涂层,进行了微观结构,形貌,纳米硬度以及耐腐蚀性能进行了表征与测试.结果表明,在O2氛围作用下,涂层相结构由fcc完全转变为bcc结构;随O2流量由0 mL/min增至15 mL/min,涂层......
Effect of Substrate and Annealing Temperatures on Mechanical Properties of Ti-rich NiTi FilmsA.Kumar1,S.K.Sharma2,S.Bysakh3,S.V.Kamat1,S.Mohan21. Defence Metallurgical Research Laboratory2.

with nanocrystallines, and the crystallization was improved with the increase of bias voltage. The hardness of Ti films measured by nanoindentation tests shows a linear relationship with grain sizes... was discussed. The nanoindentation tests were carried out to explore the Hall-Petch relationship extending grain size to several nanometers scales. 2 Experimental Ti films were deposited on (100) monocrystal......
of hardness and elastic modulus of the coating were determined by nanoindentation. The results show that the composite coating is dense and has not laminar structure. The grains of coating solidify rapidly...): 113-116. XUE Wen-bin, WANG Chao, LI Yong-liang, et al. Nanoindentation of micro-arc oxidation coatings on pure titanium[J].
