GB/T44536—2024

前言

本文件按照GB/T1.1—2020《标准化工作导则第1部分：标准化文件的结构和起草规则》的规

定起草。

本文件修改采用ISO23458：2020《精细陶瓷（先进陶瓷、先进技术陶瓷）

CVD陶瓷涂层热膨胀

系数和残余应力的测试方法》。

本文件与ISO23458：2020的技术差异及其原因如下：

—将ISO23458：2020中3.2的术语由“线热膨胀系数”更改为“残余应力”，因规范性引用文件

已对“线热膨胀系数”有所说明，本文件更有必要对“残余应力”进行定义（见3.2）；

—用规范性引用的GB/T16535替换了ISO17139，以适应我国技术条件，增加可操作性（见第

5章）；

—用规范性引用的GB/T16839.1替换了IEC60584﹘1，以适应我国技术条件，增加可操作性（见

5.3）；

—将ISO23458：2020中5.4的叙述简化为“按照GB/T16535的规定安装试样”，以标准作为依

照，提高操作规范性（见5.4）；

—用规范性引用的GB/T1216替换了ISO3611，以适应我国技术条件，增加可操作性（见5.6）；

—用规范性引用的GB/T39686、GB/T39828替换了ISO19603，以适应我国技术条件，增加可

操作性（见7.2）；

—删除了ISO23458：2020中7.4的CVD陶瓷涂层残余应力的计算，因其无须试验操作且在8.2中

已有所体现。

本文件做了下列编辑性改动：

—为与现有标准协调，将标准名称改为《CVD陶瓷涂层热膨胀系数和残余应力试验方法》。

请注意本文件的某些内容可能涉及专利。本文件的发布机构不承担识别专利的责任。

GB/T44536—2024

CVD陶瓷涂层热膨胀系数和残余

应力试验方法

1范围

本文件描述了CVD陶瓷涂层（涂层厚度大于0.03mm，且涂层厚度比基体与涂层总厚度的值小于

1/4）从室温到2300K的热膨胀系数和残余应力的测试方法，并规定了试样制备方法、加载模式、加载

速率、数据收集以及报告格式。

本文件适用于金属基体或陶瓷基体上的CVD陶瓷涂层。本试验方法可用于材料性能研究、质量控

制、性能表征以及数据采集等方向。

2规范性引用文件

下列文件中的内容通过文中的规范性引用而构成本文件必不可少的条款。其中，注日期的引用文

件，仅该日期对应的版本适用于本文件；不注日期的引用文件，其最新版本（包括所有的修改单）适用

于本文件。

3术语和定义

下列术语和定义适用于本文件。

3.1

相对法relativemethod

通过间接的方法来获得无法直接测量的参数。

注：未知参数A无法直接测量得到，但是参数B和C是已知或容易测量的。通过建立解析关系式A=f（B,C），计

算出参数A。

3.2

残余应力residualstress

消除外力或不均匀的温度场等作用后仍留在物体内的自相平衡的内应力。

4原理

涂层试样在加热或冷却过程中的变形涉及两个影响因素，即涂层和基体的热膨胀系数和残余应力。

热膨胀系数是材料的本征物理参数，而涂层的残余应力取决于材料的本征性能、构件的尺寸和涂层与基

体的横截面积比。
