標準解讀
《GB/T 44536-2024 CVD陶瓷涂層熱膨脹系數(shù)和殘余應(yīng)力試驗方法》是一項國家標準,旨在為化學(xué)氣相沉積(CVD)制備的陶瓷涂層提供一套系統(tǒng)的測試其熱膨脹系數(shù)及殘余應(yīng)力的方法。該標準適用于各種基體材料上通過CVD工藝形成的陶瓷涂層。
對于熱膨脹系數(shù)的測定,標準推薦使用了基于光學(xué)或機械測量原理的技術(shù)手段,比如熱機械分析儀(TMA)。在進行實驗時,首先需要準備具有代表性的樣品,并確保其表面清潔無污染。然后,在控制條件下加熱樣品,同時記錄隨溫度變化而產(chǎn)生的長度變化數(shù)據(jù)。根據(jù)這些數(shù)據(jù)可以計算出材料的平均線性熱膨脹系數(shù)。此外,還應(yīng)考慮不同溫度區(qū)間內(nèi)可能存在的非線性行為,以及由此帶來的誤差分析。
關(guān)于殘余應(yīng)力的評估,則提出了多種技術(shù)路線供選擇,包括X射線衍射法、拉曼光譜法等非破壞性檢測方法。每種方法都有其適用范圍和技術(shù)要求。例如,采用X射線衍射技術(shù)時,需選取合適的晶面作為測試對象;利用拉曼光譜法則要關(guān)注特定頻率范圍內(nèi)峰位移的變化情況。無論采取哪種方式,關(guān)鍵在于準確地識別并量化由于內(nèi)部應(yīng)力導(dǎo)致的微觀結(jié)構(gòu)變化。
在整個過程中,標準強調(diào)了對實驗條件(如溫度、濕度)、設(shè)備校準狀態(tài)以及操作人員技能水平等方面的要求,以保證結(jié)果的一致性和可比性。此外,還提供了詳細的步驟說明、注意事項以及數(shù)據(jù)處理建議,幫助用戶更好地理解和執(zhí)行相關(guān)測試。

前言
本文件按照GB/T1.1—2020《標準化工作導(dǎo)則第1部分:標準化文件的結(jié)構(gòu)和起草規(guī)則》的規(guī)
定起草。
本文件修改采用ISO23458:2020《精細陶瓷(先進陶瓷、先進技術(shù)陶瓷)
CVD陶瓷涂層熱膨脹
系數(shù)和殘余應(yīng)力的測試方法》。
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“線熱膨脹系數(shù)”有所說明,本文件更有必要對“殘余應(yīng)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(yīng)我國技術(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)我國技術(shù)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(yīng)我國技術(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)我國技術(shù)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(yīng)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(diào),將標準名稱改為《CVD陶瓷涂層熱膨脹系數(shù)和殘余應(yīng)力試驗方法》。
