1、XX大学毕业设计(论文)题 目: 渗透检测工艺方法和环境对检测结果的影响学 院: 测试与光电工程学院专业名称: 测控技术与仪器班级学号: 学生姓名: 指导教师: 二Oxx 年 六 月 渗透检测工艺方法和环境对检测结果的影响摘要:渗透检测方法就检测原理而言比较简单。灵敏度的准确性是人们主要考虑的一个问题,而渗透检测的可靠性及影响可靠性的因素就显得尤为重要了。渗透检测有着其自己的优势( 可检测非铁磁性材料) 有其适用性及存在的合理性。研究渗透检测灵敏度影响因素,提高其检测灵敏度即可提高其可靠性,可以让渗透检测的发挥有更大的空间。影响渗透检测灵敏度及可靠性的因素有很多,在渗透检测过程中,工件是否预清
2、洗,操作的方法问题,操作的环境改变等都会影响缺陷的检出,从而产生漏检。为了提高渗透检测的灵敏度,应采取有效措施,改变操作方法和环境条件,以满足工艺要求。本次实验主要通过研究B型试块在不同温度下的缺陷显示情况来研究操作环境的改变的影响,以及钢板焊缝两种操作检测方法的选择和是否预清洗的缺陷显示情况来研究操作方法不同和工件是否预清洗的影响。通过这次几个实验,可以掌握更多影响渗透检测灵敏度及可靠性的因素,从而做到提高渗透检测的灵敏度及可靠性。关键词:渗透检测 灵敏度渗透 操作方法 环境温度The influence of the method and environment of the penetr
3、ation to the detection resultsAbstract:The penetration detection method is relatively simple in terms of detectionprinciple. The accuracy of the sensitivity is a problem that people mainly consider,and the reliability of the penetration detection and the factor of affecting the reliability are very
4、important. Although the penetration of low detection sensitivity, reliability is not high, but in any case penetrant testing have their own advantage (which candetect the non ferromagnetic materials) has its applicability and rationality of the existence. To improve the reliability of the detection
5、sensitivity can be improve by the sensitivity of the penetration detection, so that the penetration detection can play a grater space. Affect the penetration detection sensitivity and reliability of many factors, in peNetrant testing process, operation method, operation environment change will affec
6、ts the defect detection, resulting in missing. In order to improve the sensitivity of the penetrationdetection, we should take effective measures to change the operation methodand environmental conditions to meet the process requirements. This experiment mainly through the study of B type test defec
7、ts under different temperature display to study the operation methods and different workpiece is not pre cleaning of effect. Through this experiment. We can master more factors that affect the sensitivity and reliability of the penetration detection, so as to improve the sensitivity and reliability
