“…Samad et al [ 66 , 67 ] dip-coated UHMWPE and UHMWPE/CNTs nancomposite coatings on air-plasma treated polyether ether ketone (PEEK) substrates. Even though, PEEK is a high-performance polymer because of its higher temperature resistance, it shows a higher wear rate and coefficient of friction (~0.3), which makes it a poor candidate for tribological applications.…”

“…Even though, PEEK is a high-performance polymer because of its higher temperature resistance, it shows a higher wear rate and coefficient of friction (~0.3), which makes it a poor candidate for tribological applications. Hence, PEEK was surface modified with UHMWPE coatings [ 66 ] to improve its tribological performance. Ball-on-disk wear tests were conducted using a 440C stainless steel ball, at different normal loads (5, 7 and 9 N) and varying sliding speeds (0.1, 0.2 and 0.5 m/s).…”

“…Substrates were placed in a Harrick Plasma Cleaner/Sterilizer under vacuum at an RF power of 30 W for approximately 5 min. Air-plasma treatment has been found to be an effective pre-treatment method, which is environmental friendly, easy to use, very flexible/adaptive, cost effective and less time consuming [ 60 , 61 , 62 , 63 , 64 , 66 , 67 , 68 , 69 , 70 , 71 , 72 ]. Air-plasma treatment helps in cleaning the surface by carbon cleaning effect and at the same time functionalizes the surface with carboxyl and hydroxyl groups which in turn increases the wettablility/surface free energy of the surface leading to an improved adhesion between the coating and the substrate.…”

“…Nanopowder solution from dip-coating: Dip-coating has been used by [ 60 , 61 , 62 , 63 , 64 , 66 , 67 ] to coat steel, aluminum and PEEK substrates with UHMWPE and UHMWPE composite coatings reinforced with CNTs. The nanopowder solution for dip coating was prepared by plasma treating the CNTs in the Harrick Plasma Cleaner/Sterilizer by uniformly spreading it out in a flat dish.…”

“…Dip coating process : Dip coating was found to be a very simple, cost effective and efficient technique to coat UHMWPE composite coatings. One of the advantages of dip coating is its, easy adaptability and ease of coating any intricate shapes irrespective of the substrate material [ 60 , 61 , 62 , 63 , 64 , 66 , 67 ]. The process for preparing the solution of UHMWPE/fillers in the decalin solvent has been specified above.…”

In the recent past, polymer coatings have gained the attention of many researchers due to their low cost, their ability to be coated easily on different substrates, low friction and good anti-corrosion properties. Various polymers such as polytetrafluroethylene (PTFE), polyether ether ketone (PEEK), polymethylmethacrylate (PMMA), polyurethane (PU), polyamide (PA), epoxy and ultra-high molecular weight polytheylene (UHMWPE) have been used to develop these coatings to modify the surfaces of different components to protect them from wear and corrosion. However, among all these polymers, UHMWPE stands out as a tribologist’s polymer due to its low friction and high wear resistance. These coatings have found their way into applications ranging from microelectro mechanical systems (MEMS) to demanding tribological applications such as bearings and biomedical applications. Despite its excellent tribological properties, UHMWPE suffers from limitations such as low load bearing capacity and low thermal stability. To overcome these challenges researchers have developed various routes such as developing UHMWPE composite and hybrid composite coatings with several types of nano/micro fillers, developing composite films system and developing dual film systems. The present paper is an effort to summarize these various routes adopted by different researchers to improve the tribological performance of UHMWPE coatings.
