How to judge whether the surface of the workpiece is nickel-plating or chromium-plating

A. Sulfuric Acid (H₂SO₄) Test Nickel: Dissolves slowly, producing hydrogen bubbles. Chromium: Resists sulfuric acid (no bubbles). B. Copper Sulfate Test Nickel: Immerse in 5% CuSO₄ solution → No copper deposition (nickel is more noble than copper).

How to choose electroless nickel or electroplating nickel process according to the actual demand?

For precision, wear resistance, and complex parts → Electroless Nickel (EN). For cost-sensitive, high-speed, or decorative plating → Electrolytic Nickel. For non-conductive materials → Only EN is feasible.

Analysis of the reasons for the non-plating of chemical nickel in blind holes in workpieces

Stagnant Solution → Blind holes trap air and prevent fresh plating solution from entering. Depletion of Reactants → Nickel ions and reducing agents (hypophosphite) are consumed faster than they can diffuse into the hole. Hydrogen Gas Entrapment → H₂ bubbles generated during plating block deposition. B. Inadequate Surface Activation

Influence of impurities in the chemical nickel surface treatment on the plating of the surface

Surface Roughness & Nodules Metallic impurities (Cu, Zn) promote nodular growth, leading to a rough or bumpy surface. Particulates embed in the deposit, creating defects.

How to avoid burrs on the surface of the product in the electroless nickel plating

Mechanical Polishing/Finishing: Ensure the substrate is smooth before plating. Any rough edges or micro-burrs from machining will be amplified during plating. Deburring: Use mechanical (vibratory finishing, abrasive blasting) or chemical deburring to remove sharp edges. Cleaning & Degreasing: Remove oils, oxides, and contaminants using alkaline cleaning, acid pickling,
