| 1 | 机械热处理对新型亚稳态β钛生物合金显微组织和电化学行为的影响(英文)显示文摘研究机械热处理对新型亚稳态β钛生物合金显微组织和电化学行为的影响。机械热处理方法包括在β相转变温度下热加工处理及在相同温度固溶热处理,经不同冷却速率冷却后进行时效处理。在不同的机械热处理条件下获得具不同空间分布和等轴/拉长α和β相形貌的合金组织。这些合金组织具有不同的电化学性能。通过开路电位和动电位极化测试方法,测定合金在37℃Na Cl溶液(林格氏试剂)中的腐蚀行为。 | Mohsin Talib MOHAMMED Zahid A.KHAN M.GEETHA | 2015 | Transactions of Nonferrous Metals Society of China2015，25，3： | 3 |

| 3 | 等离子喷涂制备Al_2O_3,ZrO_2,Al_2O_3/ZrO_2和ZrO_2/Al_2O_3涂层的腐蚀性能(英文)显示文摘采用大气等离子喷涂技术在低碳钢表面制备Al_2O_3、ZrO_2、ZrO_2/Al_2O_3和Al_2O_3/ZrO_2涂层。利用扫描电镜(SEM)和X射线衍射(XRD)技术对涂层的显微组织和相组成进行分析,采用极化、盐雾和浸泡等实验手段对涂层在3.5%NaCl溶液中的腐蚀行为进行研究。结果表明,双层Al_2O_3/ZrO_2涂层比另外三种涂层具有更好的抗腐蚀性能,这主要归因于该涂层中非常少的内联孔洞和稳定的相组成。 | S.SATHISH M.GEETHA | 2016 | Transactions of Nonferrous Metals Society of China2016，26，5： | 1 |
| 4 | Computerised Gate Firing Control for 17-Level MLI using Staircase PWM显示文摘A basic 7-level MLI topology is developed and the same is extended to the 9-level then further increased to 17-levels.The developed structure minimizes the component’s count and size to draw out the system economy.Despite the various advantages of MLIs,efficiency and reliability play a major role since the usage of components is higher for getting a low Total Harmonics Distortion(THD)value.This becomes a major challenge incorporated in boosting the efficiency without affecting the THD value.Various parametric observations are done and realized for the designed 9-level and 17-level MLI,being the Total Standing Voltage(TSV),efficiency,cost function per level count,and power loss.The respective parameters are compared with several existing and modern circuits and found to be effective in their performance.A novel single-phase 17-level asymmetrical Multi-Level Inverter(MLI)topology is developed to reduce the number of overall components.The developed topology generates 17-levels by using unequal DC sources.The developed MLI is proved under various tests con-ducted experimentally for the various loads like resistive,inductive,and combinational loads.A detailed comparison is done on several factors and represented graphically represented.Further,the proposed design provides a less TSV value is 6 V_(dc),efficiency is 94.21%and cost factor per level CF/L value for both values ofαis 2.01 and 2.05 and devices count with a low THD value 41.4%with respectively. | M.Geetha R.Vijayabhasker Suresh Seetharaman | 2023 | Computer Systems Science & Engineering2023，44，1： | 0 |
