surface treatment technnology
Strong points
- Due to the lack of internal stress (motive force) which causes whiskers, whiskers do not form, making a great contribution to the stabilization of quality in electronic devices.
- Due to its good luster, it is well suited for surfacing material when good design is required.
- It is cost effective as it can be used in the existing operation of zinc plating.
Strong points
- It is completely chromium free.
- Zero Chromium S has tones close to those of colored chromate, and Zero Chromium SB has similar tones to black chromate.
- For rack-and-pinion plated items, S was superior to SB in corrosion resistance.
- Even in unplated areas the corrosion resistance is excellent.
- Example with a housing configuration
- Comparative merits of various rust-resistant coatings
Strong points
- Low cost combined with superior corrosion resistance
- No whisker formation with stationary or revolving methods
Strong points
- Applying a basecoat of copper brings out the luster while providing superior corrosion resistance.
- The anti-abrasion advantage coupled with the degree of hardness make this excellent for electronics and it is also suitable for a variety of industrial parts.
Strong points
- The nickel-phosphorous alloy type has a good gloss and has a superior leveling quality.
- A uniform coat can be obtained making this suitable for shafts etc. in office automation equipment
- Complies with RoHS regulations.
Strong points
- Hv of 5-8 in anti-gloss plating makes for a comparatively soft coat.
- Suitable for shaft and bearings machinery parts as it brings out lubricity and smoothness.
Strong points
- It has a very good adhesion factor making this well-suited for a paint undercoat.
- It complies with RoHS regulations.
