前言

本文件按照GB/T1.1—2020《標準化工作導則第1部分：標準化文件的結構和起草規(guī)則》的規(guī)

定起草。

本文件修改采用ISO23458：2020《精細陶瓷（先進陶瓷、先進技術陶瓷）

CVD陶瓷涂層熱膨脹

系數(shù)和殘余應力的測試方法》。

本文件與ISO23458：2020的技術差異及其原因如下：

—將ISO23458：2020中3.2的術語由“線熱膨脹系數(shù)”更改為“殘余應力”，因規(guī)范性引用文件

已對“線熱膨脹系數(shù)”有所說明，本文件更有必要對“殘余應力”進行定義（見3.2）；

—用規(guī)范性引用的GB/T16535替換了ISO17139，以適應我國技術條件，增加可操作性（見第

5章）；

—用規(guī)范性引用的GB/T16839.1替換了IEC60584?1，以適應我國技術條件，增加可操作性（見

5.3）；

—將ISO23458：2020中5.4的敘述簡化為“按照GB/T16535的規(guī)定安裝試樣”，以標準作為依

照，提高操作規(guī)范性（見5.4）；

—用規(guī)范性引用的GB/T1216替換了ISO3611，以適應我國技術條件，增加可操作性（見5.6）；

—用規(guī)范性引用的GB/T39686、GB/T39828替換了ISO19603，以適應我國技術條件，增加可

操作性（見7.2）；

—刪除了ISO23458：2020中7.4的CVD陶瓷涂層殘余應力的計算，因其無須試驗操作且在8.2中

已有所體現(xiàn)。

本文件做了下列編輯性改動：

—為與現(xiàn)有標準協(xié)調，將標準名稱改為《CVD陶瓷涂層熱膨脹系數(shù)和殘余應力試驗方法》。

GB/T44536—2024

CVD陶瓷涂層熱膨脹系數(shù)和殘余

應力試驗方法

1范圍

本文件描述了CVD陶瓷涂層（涂層厚度大于0.03mm，且涂層厚度比基體與涂層總厚度的值小于

1/4）從室溫到2300K的熱膨脹系數(shù)和殘余應力的測試方法，并規(guī)定了試樣制備方法、加載模式、加載

速率、數(shù)據收集以及報告格式。

本文件適用于金屬基體或陶瓷基體上的CVD陶瓷涂層。本試驗方法可用于材料性能研究、質量控

制、性能表征以及數(shù)據采集等方向。
