查询词典 corrosion resisting

Ion implantation of 3×10〓/cm〓 Y can slightly shorten the initiation stage, but has no obvious effects on the long period hot corrosion behavior of alloy M41. After corroded for 100 hours at 900 ℃, the gas aluminide coating of alloy M41 didn't initiate accelerated hot corrosion, but the coating has been seriously destroyed.

表面注入剂量为3×10〓／cm〓的Y略微缩短M41合金热腐蚀的孕育期，但对长时间的热腐蚀影响不大。M41合金气相渗铝涂层热腐蚀100h后，没出现加速热腐蚀，但涂层破坏严重。

The results show that the samples exposed to the air previously for 24 h can be passivated automatically in acetic acid solution with Cl- with the corrosion potential remaining 100mV.No such phenomenon was observed for samples which were cathodically polarized with the corrosion potential stabilizing at a value of -242±3mv. The passive film formed by anodically polarizing is more proof than formed in the air.

研究还发现：在空气中放置24小时后的试样在Cl-醋酸溶液中能自钝化，自腐蚀电位为100mv；经阴极极化后的试样在Cl-醋酸溶液中不能自钝化，其自腐蚀电位为-242±3mv；经阳极极化形成的钝化膜比在空气中自然形成的钝化膜更致密。

The hygienic and toxinfree Xinli PP-R pipes serial products are green and environmental construction materials, which have been recommended by the four ministries and commissions of the State Department, The products are heatresistant which means that the temperature of the supplied water can reach 95℃ under the specified long-term working hours, They are also corrosion-resistant and antiscale and can prevent any corrosion and rust in pipes, lavers and bathtubs.

&鑫利&PPR给水管系列产品，质量轻，20℃时的密度为0.89—0.91g/cm3，重量仅为钢管的九分之一，紫铜管的十分之一。由于重量轻，可大大减轻工人的施工强度。耐热性能好：瞬间使用水温可达95℃，长期使用时，当工作压力不大于0.6mpa时，水温可达75℃。这可满足一般生活、生产水温的需要，所以建筑给水PPR管一种较理想的热水管材。耐腐蚀性好：对水中的所有离子和建筑物内的化学物质均不起化学作用，不生锈、不会腐蚀。
