因素条件对红外吸收法测试钛合金中氢含量的影响
Influence of Factors and Conditions on the Infrared Absorption Method for Testing Hydrogen Content in Titanium Alloys
摘要
Abstract
This article uses pulse furnace inert gas melting infrared absorption method to test the hydrogen content in titanium alloy,and studies the effects of seven factors and conditions on hydrogen content testing of titanium alloys:sample processing method,sample placement time,sample storage method,ultrasonic time,type of sample cleaning agent,analysis power,and flux dosage.The test conditions for testing hydrogen content in titanium alloys using infrared absorption method have been determined:precision lathe or acid washing treatment samples,acetone or anhydrous ethanol ultrasonic cleaning of the samples for 1 minute,cold air drying,and room temperature sealing storage.The analysis power of 3500 W and half piece of tin flux were used,and the samples were analyzed within 4 hours as much as possible to achieve the determination of hydrogen content in titanium and titanium alloys using infrared absorption method.The measurement results were within the uncertainty range of the standard value with relative standard deviation less than 4%(RSD,n=6 analysis result).And using this method to determine the hydrogen content of titanium and titanium alloy samples has the advantages of simple operation,high testing efficiency,low cost,good stability,and high accuracy.关键词
