Stawarczyk B, Bähr N, Beuer F, Wimmer T, Eichberger M, Gernet W, Jahn D, Schmidlin PR (2014) Influence of plasma pretreatment on shear bond strength of self-adhesive resin cements to polyetheretherketone. Femtosecond and Nd-YAG laser treatments are viable surface modification alternatives to the sulfuric acid treatment for the PEEK material. Individual Pearson correlation tests were executed for all surface treatment groups to determine any significant correlations among roughness, contact angle, and bond strength parameters ( P .05) however, significant correlations were determined between the contact angle and surface roughness values for the P and FS groups ( P < .05). Data were analyzed with the Welch test for roughness, contact angle, and bond strength parameters. After the surface treatments, the specimens were checked for roughness, contact angle, and bond strength of the composite-veneer material. The specimens were divided into five groups with different surface treatments: no treatment (NO) (control group), sulfuric acid (SA), plasma (P), femtosecond laser (FS), and Nd-YAG laser (NY). Fifty-five specimens ( n = 11) with a size of 7 × 7 × 2 mm were cut out from PEEK discs. Peeling resistance: the PEEK good peeling resistance and therefore can be made of coated thin wires or magnet wire, and can be used under harsh conditions.This study aimed to evaluate the effects of different surface modification methods on the surface roughness, contact angle, and bond strength of composite-veneer materials of polyether-ether-ketone (PEEK). The proportion of each carbon fiber, graphite, PTFE mixed modified PEEK better self-lubricating properties.Ĥ resistance to chemicals (resistance to corrosion): the PEEK product has excellent chemical resistance, it only concentrated sulfuric acid, can be dissolved or destroyed in the usual chemicals, its corrosion resistance of steel and nickel are similar.ĥ.Flame resistance: PEEK is very stable polymer 1.45mm thick samples, without any flame retardants can achieve the highest flame retardant standards.Ħ. Especially its alternating stress of excellent fatigue resistance is the most outstanding in all plastic, can be comparable with alloys.ģ.Self-lubricating: PEEK products in all plastic has outstanding sliding properties suitable for the stringent requirements of low coefficient of friction and abrasion use. Mechanical properties: PEEK plastic toughness and rigidity, and to strike a balance.
Load heat distortion temperature up to 316 ° C continuous use temperature of 260 ° C.Ģ. high temperature: the PEEK product having a higher glass transition temperature (143 ° C) and melting point (334 ° C) This is one of the reasons that it can heat resistance requirements in the use of reliable applications. The superior performance of the PEEK material is mainly manifested in the following aspects:ġ.
to further improve the lubricating properties and mechanical strength.
It has good mechanical properties and resistance to chemicals, resistance to abrasion, resistance to hydrolysis and other properties its light weight, self-lubricating properties, and having a very good flow properties and processing properties, can be filled with carbon fiber, graphite, molybdenum disulfide, etc. Polyether ether ketone (PEEK) is a high-temperature, high-performance thermoplastic special engineering plastics.
