알루미늄 기판의 무전해 니켈-구리-인 합금도금에 관한 연구(I) 전해액 및 열처리 조건이 무전해 니켈-구리-인 도금층의 제 물성에 미치는 영향
A Study on the Electroless Ni-Cu-P Alloy Plating of Al Base Hard Disk(I)Effect on some Properties of Electroless Ni-Cu-P Deposits by Electrolyte and Heat Treatment Condition
초록
Electroless Ni-Cu-P alloy plating of Al base hard disk was performed to investigate some properties according to the change of composition. It was found that the composition of Ni and Cu in deposits changed linearly with increasing the mole ratio of NiSO4.6H2O/CuSO4.5H2O. The increase in hardness by heat - treatment was confirmed to be associated with small size grained crystallization of the amorphous deposits. Acid resistance of all deposits layer. which had been heated up to 30
