“…The press fit connection with bone cement or nails should be used in bearing shell. Bearing-head system is the most vulnerable to tribological destruction part of a total hip endoprosthesis [25]. Therefore a couple of metal (Co-Cr-Mo alloy) -ceramic materials used, due to its good biotribological properties, is a good component of the whole artificial implant.…”

Dynamic development of various industries is tightly coupled with development of new technologies and materials which are increasingly dedicated for a particular application. This regards also titanium materials, which were often applied in aerospace and maritime industries. Gradually their applications spread into automotive, energy, civil engineering industries and medicine. Titanium and its alloys are characterized by unique properties that facilitates their wide adoption in different industries. Initially application of titanium materials was constrained by its high production and processing costs. The factors contributing to application of titanium in civil engineering include high corrosion resistance, low density and low thermal conductivity. High resistance to the elements is very important when durability and long term maintenance costs of a structure are considered. In case of components exposed to action of sea water, acid rains, pollutions, application of titanium materials is advantageous in long term perspective despite its high initial costs. Additionally titanium doesn’t require protective anticorrosive coatings unlike steels and copper. Titanium sheets are applied to large area architectural structures. There are many examples of technical grade titanium applications in building elevations and roofs. For these purposes thin (0.3÷3.0 mm) sheets are selected which allow for weight reduction. In this work properties of commercially pure titanium Grade 2, 3 and 4 were researched. During experimental research the following technological and mechanical properties were determined: offset yield strength Rp02, ultimate tensile strength Rm, elongation A, planar anisotropy Δr, normal anisotropy r, and strain-hardening exponent n.

“…It should be noted that excessive cross-linking, in addition to generating a large amount of free radicals, reduces the impact toughness of the material [2,23]. The optimal dose of radiation increases the wear resistance, while at the same time maintaining the required mechanical properties [5,7]. The use of selective cross-linking can be seen to be interesting, the idea of which is to radiate only some areas of the polyethylene [18].…”

The review describes the known and most common modifications to various polymers in surgical applications. A short history of the plastics used as sliding materials in endoprostheses is presented. The unsuccessful attempts of using materials in joint alloplastic, such as PMMA, POM, PTFE and PEEK, as well as their modifications, were analyzed. Many polymers with excellent sliding properties cannot be used in joint arthroplasty due to allergic, toxicological reactions or technological problems. Attention was focused on PE-UHMW polyethylene, and also its modifications that increase its wear resistance and mechanical strength. The paper summarizes the wear rates of polyethylene subjected to various types of modification, such as plastic working, crosslinking, or carbon fiber reinforcement. The latest trends for improving polyethylene are also described. Modification of polymers in joint arthroplasty. A significant advance would be to obtain PEEK that is suitable for use in arthroplasty without negative consequences. An important direction of development in the area of sliding biomaterials may also concern materials obtained by incremental methods (3D printing).
