Ionbond PVD and PACVD coating processes are environmentally friendly as there are no toxic materials involved and no harmful byproducts generated. This makes them ideal alternatives to commonly used electroplating, in particular to hard chroming that leaves poisonous residues.

Hard chromium replacement

Ionbond’s Tribobond™ series of PVD metal nitride and PACVD DLC coatings have been proven to be very effective in replacement of hard chromium plating in applications, where increased wear protection is required. These coatings provide outstanding protection against fretting, galling and abrasion, thereby clearly outperforming galvanic coatings. Tribobond™ coatings with a typical thickness of 5–10 microns are much thinner than hard chromium, offer increased hardness, a reduced coefficient of friction and enhanced adhesion. Unlike chromium plating, fine features like threads, recesses etc. are maintained and no post-grinding is required.

Tribobond™ 66 Al has shown very good results in many applications where traditionally electroplated Cd has been used for corrosion protection. The PVD process allows for oxygen free deposition of high purity aluminum with excellent uniformity, adhesion and corrosion protection. Tribobond 66 Al shows comparable characteristics to IVD (ion vapour deposition) Al coatings with resistance to corrosion in salt spray testing of over 200 hours without the need for chromic conversion post processing.

Solid lubricants

The low friction properties of Tribobond™ DLC coatings enable engineering solutions that reduce or avoid the need for lubrication. The benefit shows in the limited or eliminated need for servicing and the lower consumption of lubricants.

Corrosion barriers

Smart coating solutions can slow down corrosion, which leads to a longer lifetime of components before they have to be discarded and less corrosion products in the natural environment.
