The formation of "black layer" is also controlled by the nitrogenpotential and system temperature in the deposition chamber.
同时,“黑色层”能否形成还与气氛氮势、体系温度有关。

Higher nitrogenpotential may promote formation of white layer, increase hardness and wear resistance but at the same time increase brittleness of nitriding case.
提高氮势可促使白层形成,提高渗层硬度和耐磨性,但使其脆性增高。

Excess nitrogen and phosphorus nutrients due to large quantities of feed imports, can lead to problems with manure disposal and pose a potential pollution risk.
