Experimental design of XRD testing based on three-axis sample stage
X-ray diffraction(XRD)is the most important and fundamental testing method for modem material analysis.However,there are many strict conditions for sample preparation and testing when the standard flat sample stage is used.For example,a certain amount of powder samples is required,and block sample should meet certain size requirements.To solve the problem of complex sample preparation process in flat sample stage,an XYZ program automatic 3-axis sample stage based on polycrystalline X-ray diffractometer was designed for experimental design of powder and bulk samples.The results showed that the testing could be normally performed when the amount of powder sample was little or the size of block sample was small.Moreover,the measurement data were accurate and the operation was simple.The three-axis sample stage effectively solved the problem of small sample amount for scientific research through the combination of laser positio-ning and manual positioning.It was sample friendly.The sample preparation time was greatly shortened,which provided convenience for more efficient open and sharing.
