熱處理工藝: 水蒸氣氧化處理 (借助高溫水蒸氣在產(chǎn)品表面形成Fe3O4黑色氧化膜)
Heat Treatment: Steam Oxidizing Surface Treatment (Black oxide film of Fe3O4 is formed by high-temperature)
氧化爐 (黑化爐) 優(yōu)點:
于氮化層 (白亮層) 上形成黑色氧化膜 (Fe3O4),帶有光澤,質(zhì)地均勻,無色差。氮化氧化復合膜 (Oxy-Coat),借助于氧化膜的封孔作用,提高工件的耐腐蝕性,耐磨性,耐容損性等。使用水蒸氣處理,對人體及環(huán)境無害。
Advantages of Using Steam Oxidizing Furnace:
The black oxide film (Fe3O4) formed on the nitride layer is glossy, uniform and cause no color differences. The film of Oxy-Coat can improve the corrosion resistance, wear resistance and solution resistance, etc. by the pore sealing effects. Stream treatment is harmless to human bodies and environment-friendly.
