氧氮氢分析仪的常见故障及解决方法

供电正常、通讯正常，点击确认键后分析仪不工作。这是没有水流，炉子温度太高或仪器通道电压不正常。如没有水流，炉子温度太高这些信息会显示在显示器画面上，但没有信息显示说明这两项正常。接下来检查仪器通道零位电压，如果比±3V高出1V以上，可能是因为气瓶空了，或者是空气进入到分析仪中。检查并更换化学试剂，如果有空气进入热导池里，热导池的电压就会＜-6V，此时打开右面的门，堵住炉子气体进口，10s后，热导池电压值必然升高。经过逐一排查，**终确认碱石棉有问题，更换后仪器正常。 可选六轴可旋转触摸屏幕，增强了操作的工效和直观性。湖南LECO分析仪多少钱

Oxygen, Nitrogen, and Hydrogen in Refractory Metals

Summary

One of the most critical chemical specifications of titanium alloys is the hydrogen content. Too high of a

hydrogen content can cause hydrides to precipitate, which can lead to embrittlement and subsequent

cracking when the alloy is stressed. Hydrogen pickup typically occurs during downstream processing steps

such as heat treating, pickling, and cleaning.

The LECO ONH836 is a simultaneous oxygen, nitrogen, and hydrogen determinator that utilizes an electrode furnace, inert carrier gas, and both infrared and thermal conductivity detection to meet the analytical needs of the refractory metal industry. 

This application note was written specifically for use with the LECO ONH836 series determinator.

Procedure - Solid Samples

Prepare the instrument as outlined in the operator's instruction manual.

Determine the instrument blank.

Login a minimum of 3 Blank replicates.

Press the Analyze button on the instrument screen. After a short delay, the loading head slide-block will open. Place a 502-344 Nickel Basket into the loading head.

Note: samples using automation should be placed in the appropriate autoloader position before starting the

analysis sequence. Once the sequence has started, the automatic analysis will start and end automatically.

Oxygen, Nitrogen, and Hydrogen in Refractory Metals

Summary

Oxygen and nitrogen are alloying elements in titanium, and are also classified as alpha stabilizing elements as they promote alpha phase alloys. Interstitial oxygen and nitrogen levels can be used to regulate the tensile strength of the material, but due to its high solubility can cause unwanted surface embrittlement. This phenomenon can be leveraged,however, under controlled processing to create surface films that increase surface hardness and wear properties.
