Tetrabond™ Plus: best in class ta-C coating from Ionbond Korea

01 July 2021

There are many challenges when it comes to machining non ferrous materials, soft and sticky materials like aluminum, brass, copper or plastics, as well as very abrasive materials such as Glass fibers, Aluminium Silicium alloys (with Si>10%) and Carbon Reinforced Polymers (CFRP). In these demanding machining conditions, tetrahedral amorphous carbon (ta-C) coating is the ideal solution to significantly increase tool life and productivity.

Ionbond has a long experience in the field of tetrahedral amorphous carbon coatings and has successfully introduced Tetrabond™ Plus during the last years. The coating, a joint development from Ionbond plants located in Mansfield (UK) and in Daegu (Korea), exhibits a very high hardness and a low roughness compared to standard PVD arc coatings. This combination, coupled with the extended know-how of our teams, allows our customers to benefit from a highly fine-tuned portfolio of ta-C solutions ranging from 0,2µm to over 2,5µm in thickness.

This is particularly true in Ionbond Korea where the local team constantly meets the request of continuous performance improvement from their main cutting tool OEM customers through an efficient PDCA cycle.

Ionbond Korea General Manager Sang-won Lim: “The demand for non ferrous materials machining keeps increasing within the 3Cs industry (computers, communications and consumer electronics) as well as within ongoing changes in the automotive sector. Our approach of fine-tunned coatings per application is the driver for satisfied customers and for further growth. With two dedicated coating machines, we can meet the expectations of the market and also help our colleagues from other Ionbond centers.”

Ionbond Cutting Tools Global Segment Manager Mario Fusaro: “We have all been the witnesses to the rise of South Korean companies over the last decades in numerous fields, driven by high quality standards and competitive pricing. Ionbond Korea is part of this success and we are proud at Ionbond to have such a team in our network. Their entrepreneurship mindset fits perfectly with Ionbond’s DNA. Working together on technology and coating developments, we bring added value to our customers.”

Ionbond has an extended PVD and CVD coating portfolio for cutting tools application available in more than 25 centers worldwide. Tetrabond™ Plus is available in the USA, in the UK and in Korea. For more information, please contact Mario Fusaro (
