ASTM\u00a0F1978<\/a>:<\/strong>\u00a0Standard Test Method for Measuring Abrasion Resistance of Metallic Thermal Spray Coatings by Using the Taber Abraser<\/p>\n\n\n\n

The standard describes four different types of femoral stems and summarizes several considerations concerning the fatigue performance of femoral hip components and their metallic coating integrity.<\/p>\n\n\n\n

Fatigue performance can be assessed using the following standards:
ISO\u00a07206-4<\/a><\/strong>: Femoral stem fatigue test
ISO\u00a07206-6<\/a><\/strong>: Femoral neck fatigue test<\/p>\n\n\n\n

Coating integrity can be investigated regarding shear and tensile strength, and abrasion resistance of plasma sprayed thermal coatings. Standards and minimum acceptance criteria are as below:
ASTM\u00a0F1044<\/strong><\/a> \u2013 Shear strength \u2013 equal or exceeding 20 MPa
ASTM\u00a0F1147<\/strong><\/a> \u2013 Tensile strength \u2013 equal or exceeding 20 MPa
ASTM\u00a0F1978<\/strong><\/a> \u2013 Abrasion resistance \u2013 \u2264 65 mg\/100 cycles<\/p>\n\n\n\n
