EFFECT OF THE SINTERING TEMPERATURE ON TRIBOLOGICAL WEAR OF 316L AND 316L-HAp OBTAINED WITH THE USE OF SPARK PLASMA SINTERING
Journal Title: Tribologia - Year 2015, Vol 260, Issue 2
Abstract
The use of 316L stainless steel in osteoarticular system implants is associated with many operational problems. One of the methods that deal with these restrictions may be the development of new materials, including composites, using powder metallurgy. This paper presents the results obtained during tribological tests of 316L and 316L-HAp sintered materials produced with the use of the spark plasma sintering method applying various sintering temperature. The increase of the sintering temperature from 1000 to 1100°C resulted in the deterioration of the wear resistance of 316L. However, compared to solid 316L, the wear resistance of these materials was several dozen times higher. The increase of the sintering temperature resulted in the improvement of the wear resistance of 316L-HAp. The wear resistance of the composites that had been sintered at lower temperatures was comparable to the reference material.
