in Aerospace Surface Preparation<\/h2>\n  <p>Aerospace surface preparation imposes requirements that eliminate most commercially available abrasive media from consideration. Substrates include titanium alloys (Mohs 6\u20137), nickel superalloys (Mohs 6\u20138), hardened stainless steel fasteners, silicon carbide-reinforced composite (SiC\/SiC) hot section components, and carbon fiber reinforced polymer (CFRP) structures \u2014 all of which demand an abrasive that is simultaneously hard enough to achieve required surface cleanliness and profile, chemically inert enough to avoid surface contamination, and pure enough to meet strict acceptance testing.<\/p>\n  <p>Silicon carbide \u2014 specifically high-purity Green SiC in most aerospace applications \u2014 meets all three requirements. Its Mohs 9.3\u20139.5 hardness provides adequate cutting power on nickel superalloys and titanium. Its chemical inertness means no reactive species are deposited on the surface. And its very low iron content (Fe\u2082O\u2083 \u2264 0.08% for Green SiC) eliminates the risk of iron contamination that would cause galvanic corrosion on titanium or interfere with subsequent diffusion bonding, thermal barrier coating (TBC) deposition, or high-temperature brazing.<\/p>\n  <p>For a full overview of SiC properties: <a href=\"https:\/\/hlh-js.com\/resource\/blog\/silicon-carbide-abrasive-blasting-media-complete-buyers-guide\/\" target=\"_blank\" rel=\"noopener\">Complete Buyer&#8217;s Guide to SiC Abrasive Blasting Media<\/a>.<\/p>\n  <div class=\"hlh-tags\">\n    <span class=\"hlh-tag\">MIL-SPEC<\/span>\n    <span class=\"hlh-tag\">NADCAP<\/span>\n    <span class=\"hlh-tag\">Ti-6Al-4V<\/span>\n    <span class=\"hlh-tag\">Inconel<\/span>\n    <span class=\"hlh-tag\">CFRP<\/span>\n    <span class=\"hlh-tag\">TBC Prep<\/span>\n    <span class=\"hlh-tag\">AS9100<\/span>\n  <\/div>\n<\/div>\n\n<hr class=\"hlh-divider\">\n\n<div class=\"hlh-section\">\n  <span class=\"hlh-section-anchor\" id=\"standards\"><\/span>\n  <h2><span class=\"hlh-h2-num\">SECTION 02<\/span>Applicable Standards for Aerospace Abrasive Blasting<\/h2>\n  <p>Aerospace abrasive blasting operations are governed by a layered hierarchy of standards \u2014 from international quality management system standards at the top to substrate-specific process specifications at the component level.

These properties drive two critical requirements for SiC media used on titanium:<\/p>\n  <h3>Iron Contamination Control<\/h3>\n  <p>Iron contamination on titanium surfaces creates galvanic cells that accelerate corrosion under salt fog or high-humidity service conditions \u2014 a critical failure mode for airframe structural components. Silicon carbide media used on titanium must have a documented Fe\u2082O\u2083 content \u2264 0.08% (Green SiC specification). Media must also be stored and used in dedicated, iron-free equipment (no steel blast pots, no steel media previously used in the equipment). Post-blast inspection for iron contamination is typically performed using the ferroxyl test (blue-spot test) or high-resolution XRF surface analysis.<\/p>\n  <h3>Hydrogen Embrittlement Risk<\/h3>\n  <p>Titanium alloys are susceptible to hydrogen embrittlement at elevated temperatures from abrasive impact. High-pressure blasting (above 80 PSI) generates localized surface heating during impact that can cause hydrogen absorption from moisture in the blast air. For Ti-6Al-4V and other alpha-beta titanium alloys, limit blast pressure to 60\u201370 PSI maximum, maintain air dew point below \u221240\u00b0C at the nozzle, and conduct blasting in a temperature-controlled environment (15\u201325\u00b0C ambient).<\/p>\n  <div class=\"hlh-highlight\">\n    <p><strong>Recommended specification for Ti-6Al-4V:<\/strong> Green SiC #120\u2013150, 45\u201365 PSI direct pressure, 200 mm standoff, 85\u201390\u00b0 nozzle angle, air dew point \u2264 \u221240\u00b0C, boron carbide nozzle.

Surface preparation of these components prior to thermal barrier coating (TBC) deposition is one of the most demanding applications for SiC abrasive blasting \u2014 the surface profile created by blasting directly determines the bond strength and long-term spallation resistance of the TBC.<\/p>\n  <p>For TBC applications on nickel superalloys, the target surface profile is typically Ra 3\u20138 \u00b5m (Rz 18\u201345 \u00b5m), depending on the specific bond coat system (MCrAlY, Pt-aluminide, or YSZ). SiC #80\u2013120 grit at 60\u201380 PSI direct pressure achieves this profile range effectively on Inconel 718 (Mohs ~7\u20138). The surface must be blasted immediately before bond coat deposition (no more than 4 hours before, per most TBC process specifications) to prevent re-oxidation of the active surface.<\/p>\n<\/div>\n\n<hr class=\"hlh-divider\">\n\n<div class=\"hlh-section\">\n  <span class=\"hlh-section-anchor\" id=\"composites\"><\/span>\n  <h2><span class=\"hlh-h2-num\">SECTION 07<\/span>CFRP and Structural Composites<\/h2>\n  <p>Carbon fiber reinforced polymer (CFRP) composites present a unique challenge for abrasive blasting \u2014 the fiber-resin interface is sensitive to impact energy, and excessive blast pressure can cause subsurface delamination, fiber breakage, or matrix cracking that is not visible on the surface but creates structural weaknesses. Abrasive blasting of CFRP is typically limited to surface resin removal, adhesive bond preparation, and paint adhesion profiling \u2014 not aggressive material removal.<\/p>\n  <p>For CFRP, SiC at fine grit (#150\u2013240) and carefully controlled low pressure (25\u201350 PSI) with a large standoff (300\u2013450 mm) is used to gently abrade the surface resin without disturbing the fiber architecture.
