ANKOR 1126
Hard chromium electrolyte
-------------------ANKOR 1126 硬鉻電解液
CHARACTERISTICS【簡介】
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.硬質(zhì)鉻電解液具有較高的陰極電流效率和良好的拋擲能力，可沉積硬度約為1050 HV 0,1的微裂紋沉積。ANKOR 1126結(jié)合了傳統(tǒng)硫酸電解質(zhì)的良好性能，即只有輕微的鐵和鐵合金的攻擊和陰極電流效率，這通常只有催化劑在配合氟化物的基礎(chǔ)上實(shí)現(xiàn)。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).與基于硫酸或混合鍍鉻溶液的使用壽命相比，鉛合金陽極的使用壽命較短，并取決于個(gè)人的操作條件。新的陽極必須按照說明書MB0021中的描述進(jìn)行加工。此外，建議使用鍍鉑鈦陽極。必須當(dāng)心，它們完全覆蓋了一層二氧化鉛薄膜(棕黑色層)。只有在此條件下，Cr3+才被氧化為Cr6+。使用一個(gè)或多個(gè)PbSn陽極和鍍鉑鈦陽極或通過添加ANKOR添加溶液PTA(見技術(shù)數(shù)據(jù)表)獲得二氧化鉛薄膜。
Voltage電壓
The required rectifier voltage depends on various factors, e.g. current density, concentration, temperature, type of electrode and electrode spacing. Average value: 6 - 12V.所需的整流電壓取決于各種因素，如電流密度、濃度、溫度、電極類型和電極間距。平均值:6 - 12V。
Rectifiers整流器
Usually 12 volt units; for high outputs 15 volt units. 通常是12伏單位;高輸出15伏單位。
Rectifiers have to be adjusted until the residual ripple is less than 5 % within the total current range. 整流器必須調(diào)整，直到剩余紋波在總電流范圍內(nèi)小于5%。
Deposition rate 沉積率
At 50 A/dm2 approx.1,0 um/min chrome is deposited.
