表面結構的測量與特徵描述是精密計量技術的一個重要方面,傳統上包括將輪廓情況根據不同的波長范圍劃分為粗糙度、波紋度和形狀及后續的數字量化.按算得的參數檢查它是否為公差允許,以保證零件執行其指定的功能.當技術特性已經經過仔細確定,並且其過程穩定時,該方法是令人滿意的;但是,當製造過程正在進行中或過程的不穩定、過程變化使技術特性失效時,就需要研究和功能表現及過程評定相關的表面參數.討論了表面結構的分類與識別問題.同時闡述了為此目的而開發的先進技術及其應用.所研究的技術對從納米尺度到傳統的微米尺度的較大帶寬范圍內的表面特徵描述都是有效的The main research content of the article is involved as follows : ( 1 ) the research and discussion of the quantitative metallographic analysis methods and the measuring methods of micro hardness.
