前言

本文件按照GB/T1.1—2020《標(biāo)準(zhǔn)化工作導(dǎo)則第1部分：標(biāo)準(zhǔn)化文件的結(jié)構(gòu)和起草規(guī)則》的規(guī)

定起草。

本文件修改采用ISO23458：2020《精細(xì)陶瓷（先進(jìn)陶瓷、先進(jìn)技術(shù)陶瓷）

CVD陶瓷涂層熱膨脹

系數(shù)和殘余應(yīng)力的測(cè)試方法》。

本文件與ISO23458：2020的技術(shù)差異及其原因如下：

—將ISO23458：2020中3.2的術(shù)語(yǔ)由“線熱膨脹系數(shù)”更改為“殘余應(yīng)力”，因規(guī)范性引用文件

已對(duì)“線熱膨脹系數(shù)”有所說(shuō)明，本文件更有必要對(duì)“殘余應(yīng)力”進(jìn)行定義（見3.2）；

—用規(guī)范性引用的GB/T16535替換了ISO17139，以適應(yīng)我國(guó)技術(shù)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(yīng)我國(guó)技術(shù)條件，增加可操作性（見

5.3）；

—將ISO23458：2020中5.4的敘述簡(jiǎn)化為“按照GB/T16535的規(guī)定安裝試樣”，以標(biāo)準(zhǔn)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(yīng)我國(guó)技術(shù)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(yīng)我國(guó)技術(shù)條件，增加可

操作性（見7.2）；

—?jiǎng)h除了ISO23458：2020中7.4的CVD陶瓷涂層殘余應(yīng)力的計(jì)算，因其無(wú)須試驗(yàn)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(dòng)：

—為與現(xiàn)有標(biāo)準(zhǔn)協(xié)調(diào)，將標(biāo)準(zhǔn)名稱改為《CVD陶瓷涂層熱膨脹系數(shù)和殘余應(yīng)力試驗(yàn)方法》。
