- 導言 木馬金相砂紙耐水性好，經久耐用，使用壽命長。沙粒 表麵均勻，優異的磨削特性可以最大限度地減少樣品的變形。 金相砂紙由精選、大小均勻的碳化矽磨粒製成，具有優良的 研磨效果。采用靜電打磨工藝製成的耐水金相砂紙具有 磨粒分布均勻，磨削鋒利，經久耐用的...
切割是材料分析的第一步。切割機和切割輪的選擇必須符合試樣的幾何尺寸和材料特性。完美的金相切削應避免顯微組織熱損傷和變形，並保持必要的精度和效率。
硬度和延展性是選擇切割輪的兩個主要參數。切割輪的最佳選擇取決於材料的尺寸、硬度和延展性以及所用設備。特洛伊的切割產品用事實說話，切割過程簡單、快速、準確。
拋光是用少量的拋光粉或拋光液放在拋光布上，然後對樣品進行拋光。拋光的目的是去除研磨過程中的變形和劃痕，從而產生劃痕的鏡麵，以便微觀分析微觀結構。
