<p>热喷涂钛酸钡（BaTiO₃）涂层是一种兼具功能特性与结构优势的先进陶瓷涂层，广泛适用于高介电环境。</p>



<h3 class="wp-block-heading">‌<strong>核心性能特征</strong>‌</h3>



<ul class="wp-block-list">
<li>‌<strong>力学性能</strong>‌：<br>采用等离子热喷涂工艺制备的钛酸钡涂层，其显微硬度可达 ‌<strong>550 HV</strong>‌，结合强度高于 ‌<strong>40 MPa</strong>‌，孔隙率可低至 ‌<strong>2%</strong>‌，表明其具备良好的致密性与基体附着力，满足基本工程服役需求。</li>



<li>‌<strong>电学与铁电性能</strong>‌：
<ul class="wp-block-list">
<li>原始喷涂态涂层主要为‌<strong>非晶相</strong>‌，介电常数较低（约85）；</li>



<li>经 ‌<strong>1200℃ 热处理</strong>‌后，涂层结晶为四方相 BaTiO₃，介电常数显著提升至 ‌<strong>270</strong>‌，恢复部分铁电性；</li>



<li>压电常数（d₃₃）因喷涂高温导致晶格畸变与氧空位缺陷，‌<strong>低于块体陶瓷</strong>‌（350–380 pC/N），未达商用压电陶瓷水平；</li>



<li>介电损耗（tanδ）在热处理后可控制在合理范围，但高于新型弛豫铁电材料（如 Bi₆Ti₅WO₂₂，tanδ ~ 10⁻³）。</li>
</ul>
</li>



<li>‌<strong>相结构与工艺敏感性</strong>‌：
<ul class="wp-block-list">
<li>喷涂过程中易生成副产物如 ‌<strong>BaTi₂O₅</strong>‌，影响铁电性能；</li>



<li>等离子功率、送粉速率、喷涂距离等参数直接影响熔融颗粒的飞行状态与冷却速率，进而控制晶粒尺寸与相组成；</li>



<li>氧气气氛控制不当会加剧钛元素挥发，导致非化学计量比，降低介电性能。</li>
</ul>
</li>
</ul>



<h3 class="wp-block-heading">‌<strong>应用场景与局限性</strong>‌</h3>



<ul class="wp-block-list">
<li>‌<strong>适用领域</strong>‌：
<ul class="wp-block-list">
<li>微电子器件中的‌<strong>高介电绝缘层</strong>‌（如MLCC基板辅助层）；</li>



<li>传感器基底材料，用于‌<strong>电容式压力/位移传感</strong>‌；</li>



<li>作为‌<strong>无铅铁电材料</strong>‌研究体系，探索替代PZT的环保路径。</li>
</ul>
</li>
</ul>



<h3 class="wp-block-heading">‌<strong>微观结构与表征</strong>‌</h3>



<p>热喷涂钛酸钡涂层呈现典型的‌<strong>层状结构</strong>‌，基体与涂层间为机械结合，内部存在少量微裂纹与未熔颗粒。SEM图像显示其表面平整、孔隙率低，断面清晰可见分层沉积特征。XRD分析证实热处理前后物相由非晶向四方相BaTiO₃转变。</p>
