1) lead tin overlay
铅锡堆焊(涂层)
2) CrMnB coating
CrMnB堆焊涂层
1.
Cavitation erosion and erosion resistance of CrMnB coating was obviously better than 0Crl3NiSMo used as traditional hydraulic turbine material,but its damage process under the combination effect of erosion and cavitation was hardly investigated.
CrMnB堆焊涂层的抗空蚀和冲刷磨损能力明显优于传统水轮机用材0Cr13Ni5Mo,但目前对在冲蚀和空蚀共同作用下环境参数对其损伤机制影响的研究还很少。
3) tin-lead solders
锡铅焊料
1.
Accordling to the basic principle of GB10574-89,the method of determination of tin in tin-lead solders was studied further.
本文根据GB10 5 74- 89《碘酸钾滴定法测定锡量》的基本原理 ,对锡铅焊料中锡的测定方法做了进一步探讨。
4) tin lead soldring
锡铅钎焊
5) free-lead solder
无铅焊锡
1.
A mathematic model for evaluating the uncertainty of the determination procedure for silver in free-lead solder in electric apparatus and toys by inductively coupled plasma-atomic emission spectrometry was established.
建立了电感耦合等离子体发射光谱法测定无铅焊锡中银的数学模型,对数学模型中各个参数的不确定度来源进行评定,包括称样质量、配制标准工作溶液、工作曲线拟合、试液定容体积及测量重复性等引入的不确定度。
