Foreword

YY/T 0988 "Surgical Implant Coating" is divided into the following sections.

- Part 1. cobalt - 28 chromium - 6 molybdenum powder;

- Part 2. Titanium and titanium - 6 - 4 - vanadium alloy powders;

- Part 3 to Part 10. (reserved);

- Part 11. Test methods for tensile test of calcium phosphate coating and metal coating;

Part 12. Test methods for calcium phosphate coating and metal coating shear test;

- Part 13. Test methods for shear and bending fatigue of calcium phosphate, metal and calcium phosphate/metal composite coatings;

- Part 14. Method for evaluation of porous coating bodies;

Part 15. Test method for abrasion resistance of metallic thermal sprayed coatings. This part is part 12 of YY/T 0988.

This part is drafted in accordance with the rules given in GB/T 1.1-2009.

This part uses the re-drafting method in accordance with ASTM F1044-2005 "Calcium phosphate coating and metal coating shear test method" preparation.

The technical differences between this part and ASTM F1044-2005 are as follows.

--- on the normative reference documents, this part has made a technical differences in the adjustment to meet China's technical conditions, adjust the situation The situation is reflected in Chapter 2, "Normative references", as follows.

Replace GBME8 with GB/T 228.1 - replace GBME6 with GB/T 10623; Replace GBME4 with GB/T 16825.1.

1 Scope

This part of YY/T 0988 specifies a continuous calcium phosphate coating and a metal coating bonded to a dense metal substrate at room temperature Of the shear test method. This part is used to evaluate the degree of adhesion of the coating to the substrate in the shear form (parallel to the direction of the bond plane) Department of the degree of integration. This part adopts the International System of Units (SI).

This section does not attempt to address all the security issues involved, even those related to their use. Indeed It is the responsibility of the user of this section to establish appropriate safety and health practices and to apply the limits of management clearly before application.
