martensitic matrix [ 1 , 2 ].
After solution treatment and cooling to room temperature, 17-4 PH stainless steel shows a martensitic structure but does not exhibit high hardness [ 3 ]. The ageing in the temperature range of 480–620 °C produces a

TiO 2 film alone has some disadvantages, such as low hardness, and it can be easily destroyed under harsh conditions, such as chloric environment, which ultimately lead to release of Ni, Al, V, and the different toxic ions from the implant materials
(2006) with some modifications using Brookfield Texture Analyzer (CT3, Load cell: 4500 g) to detect hardness (g), springiness (mm), cohesiveness, and chewiness (g×mm). For TPA, 38 mm diameter of sucuk samples were cut into cylinders

beyond 50 g of the applied load, hardness test could not be carried out above this load. The length of the two diagonals of the indentations were measured on the (010) and (001) planes and the Vickers microhardness number ( H v ) was computed using the
scanning electron microscopy (FESEM). In addition, the dynamic mechanical properties, hardness, resilience and abrasion properties of the vulcanizates were also investigated.
