ANKOR 1126
Hard chromium electrolyte
-------------------ANKOR 1126 硬铬电解液
CHARACTERISTICS【简介】
Hard chromium electrolyte with high cathodic current efficiency and good throwing power for the deposition of micro-cracked deposits with a hardness of approximately 1050 HV 0,1. ANKOR 1126 combines the good properties of conventional sulphuric acid electrolytes, i.e. only slight attack of iron and iron alloys and cathodic current efficiencies which are usually only achieved with catalysts on the basis of complexed fluorides. ANKOR 1126 is free of fluorides.硬质铬电解液具有较高的阴极电流效率和良好的抛掷能力,可沉积硬度约为1050 HV 0,1的微裂纹沉积。ANKOR 1126结合了传统硫酸电解质的良好性能,即只有轻微的铁和铁合金的攻击和阴极电流效率,这通常只有催化剂在配合氟化物的基础上实现。ANKOR 1126不含氟化物。

The service life of the lead alloy anodes is shorter compared to the service life in chrome plating solutions based on sulphuric acid or mixed and is dependent upon the individual operating conditions. New anodes have to be worked in as described in the Instruction Sheet MB0021 Furthermore platinized titanium anodes are recommended . Care has to be taken that they are completely covered with a lead dioxide film(brown-black layer). Only under this condition is Cr 3+oxidised to Cr6+.The lead dioxide film is obtained using one or more PbSn anodes together with the platinized titanium anodes or by addition of ANKOR Addition Solution PTA (see Technical Data Sheet).与基于硫酸或混合镀铬溶液的使用寿命相比,铅合金阳极的使用寿命较短,并取决于个人的操作条件。新的阳极必须按照说明书MB0021中的描述进行加工。此外,建议使用镀铂钛阳极。必须当心,它们完全覆盖了一层二氧化铅薄膜(棕黑色层)。只有在此条件下,Cr3+才被氧化为Cr6+。使用一个或多个PbSn阳极和镀铂钛阳极或通过添加ANKOR添加溶液PTA(见技术数据表)获得二氧化铅薄膜。
Voltage电压
The required rectifier voltage depends on various factors, e.g. current density, concentration, temperature, type of electrode and electrode spacing. Average value: 6 - 12V.所需的整流电压取决于各种因素,如电流密度、浓度、温度、电极类型和电极间距。平均值:6 - 12V。
Rectifiers整流器
Usually 12 volt units; for high outputs 15 volt units. 通常是12伏单位;高输出15伏单位。
Rectifiers have to be adjusted until the residual ripple is less than 5 % within the total current range. 整流器必须调整,直到剩余纹波在总电流范围内小于5%。
Deposition rate 沉积率
At 50 A/dm2 approx.1,0 um/min chrome is deposited.
