How to solve the insufficient hardness dilemma of electroless nickel plating layer?

In the field of precision manufacturing, quality disputes caused by insufficient hardness of plating are common. A plating plant has feedback, customer requirements for steel workpiece hardness after nickel plating ≥ 40HRC, but the traditional process after plating only 35HRC, heat treatment barely meets the standard but accompanied by the risk of brittleness. This plating hardness and toughness of the contradiction, just the direction of the breakthrough in the phosphorus electroless nickel plating solution.  

The core advantage of Bigely Ni-809 medium phosphorus electroless nickel plating solution lies in the well-regulated coating structure through 7.5-9% phosphorus content. The phosphorus element forms a homogeneous solid solution with the amorphous nickel matrix during the deposition process, and the hardness of the plated layer can reach 48 HRC (Rockwell hardness), which can satisfy the needs of customer orders.

Another deep logic of choosing Ni-809 lies in the process stability. Its unique additive system extends the life of the plating solution to more than 10-12 cycles, and the plating speed is stabilized at 18-20 μm/h, which ensures the consistency of hardness in mass production. The case of an automobile parts factory shows that after adopting this process, the product qualification rate has been greatly improved.
