摘要： A method for quality assurance of a laser shock peening process of workpieces includes measuring and recording or temporal light intensity data over a short period during the duration of a plasma associated with the vaporized material from laser shots fired during a production laser shock peening process. The recorded temporal data is then analyzed to obtain an instantaneous optical spectrum of the plasma and then used to provide statistical control of the production laser shock peening process. One correlation function of the present invention is based on a time integrated spectral peak intensity wavelength curve for each of the laser firings and for which a peak intensity wavelength is determined for a plurality of times during each plasma of a plurality or all of the firings. Production results from the analysis of the instantaneous optical spectrum is used to determine whether the production laser shock peening process is acceptable. One embodiment of the method compares the production results from the analysis of the instantaneous optical spectrum to a correlation of test results from the analysis of instantaneous optical spectrum and high cycle fatigue failure based on high cycle fatigue tests of test workpieces that are the same or related to the production workpieces and that were laser shock peened in the same or similar laser shock peening apparatus.
摘要翻译：用于工件的激光冲击硬化处理的质量保证的方法包括在与在生产激光冲击喷丸处理过程中激发的激光照射的蒸发材料相关联的等离子体的持续时间内在短时间内测量和记录或记录光时间。然后分析记录的时间数据以获得等离子体的瞬时光谱，然后用于提供生产激光冲击喷丸处理的统计控制。本发明的一个相关函数是基于每个激光发射的时间积分光谱峰值强度波长曲线，并且在多个或所有发光的每个等离子体期间多次确定峰值强度波长。使用瞬时光谱分析的生产结果来确定生产激光冲击硬化过程是否可以接受。该方法的一个实施例将来自瞬时光谱的分析的生产结果与基于相同或相关的测试工件的高周期疲劳试验的瞬时光谱分析和高循环疲劳失效的测试结果的相关性进行比较对相同或类似的激光冲击喷丸装置进行激光冲击喷丸处理的生产工件。

摘要： An ultrasonic inspection element and method of fabrication are provided for ultrasonic inspection of curved surface parts. Various points on a transducer are located. These points include the location where a ray starts, to the desired focal point in the material being inspected. The path of the ray is through a water medium and a water-metal boundary. These points are fitted onto a cylindrical surface. The ray is back propagated until it is focused at the desired focal point.

摘要： A system and method using a touch probe device for eddy current inspection. The touch probe provides a simple approach for coming within close contact of the specimen while maintaining a normal angle and pressure at the right positions. The use of the touch probe further reduces the total time for the eddy current inspection. The touch probe aligns the probe to a specimen to be inspected, for the purpose of reducing measurement errors and increasing productivity.
