... corroded away, leaving a weak, porous residual structure. The brazing alloy was of type CP 1 as covered by BS 1845. Header and tube materials were basically copper-nickel alloys for which the use of a phosphorus bearing brazing alloy is not recommended owing to the possibility of forming the brittle...

...Abstract Abstract The paper discusses the analysis of a coating defect on a high phosphorus electroless nickel (Ni-11 wt. % P) deposit plated on an aluminum alloy substrate. Preliminary investigations had indicated that the elongated defects were possibly caused by the entrapment of long fibers...

... the presence of a continuous, pore-free nickel-phosphorus coating. This coating, which as-deposited is amorphous, crystallizes at a temperature of about 320°C ( 4 ). This process produces a two phase structure of nickel and Ni 3 P which is brittle and readily cracks. On surfaces that are heated above 350°C...
